FUNCTIONALITY

The PXM-C388 is well suited for directly upgrading existing PC/104-based designs with Intel’s Atom processor family. It

blends high-speed serial bus expansion with legacy PC/104 I/O module migration to strike a balance of high-integration

computing power for existing cost-effective applications requiring relays, digital I/O and low-to-moderate speed analog I/O.

I/O Port Map

Following is a list of I/O ports used on the PXM-C388-S.

NOTE: The PXM-C388-S uses a PnP BIOS resource allocation. Care must be taken to avoid contention with resources

allocated by the BIOS.

This product utilizes a LPC to ISA Bridge to address the PC/104 bus. The majority of legacy PC/104 modules are I/O

mapped and function as expected. However, neither DMA nor memory mapped PC/104 modules are supported with this

product. The PC/104-Plus PCI signals are completely supported.

* The ICH8M limits the LPC (ISA) decode ranges to four windows, two of which can be adjusted in the BIOS. For

example, the 0300-033Fh range can be changed to 0600-06FFh so the full 256 bytes are available for PC/104 modules.

Resources addressed internally may still exist in these ranges so please check the I/O map for availability.

The advanced watchdog timer is the only on-board device affected by adjusting LPC (ISA) decode range. It will not be

available if the 0564-0568h decode range is disabled.

The default is for the PC/104 decode ranges are shown below. Please contact an Applications Engineer if you have

questions regarding the decode ranges.

Interrupt Map

WinSystems does not provide software support for implementing the Interrupt Status

Register to share interrupts. Some operating systems, such as Windows XP and Linux,

have support for sharing serial port interrupts and examples are available. The user will

need to implement the appropriate software to share interrupts for the other devices.

Hardware Interrupts (IRQs) are supported for both PC/104 (ISA), PCI and PCIe devices. The user must reserve IRQs in

the BIOS CMOS conguration for use by legacy devices. The PCIe/PnP BIOS will use unreserved IRQs when allocating

resources during the boot process. The table below lists IRQ resources as used by the PXM-C388-S.

These IRQ references are default settings that can be changed by the user in the CMOS Settings

utility. Reference the Super I/O Control section under Intel.

**

IRQ9 is commonly used by ACPI when enabled and may be unavailable (depending on operating

system) for other uses.

*** IRQ15 is currently unavailable under the Windows operating systems.

Some IRQs can be freed for other uses if the hardware features they are assigned to are not being

used. To free an interrupt, use the CMOS setup screens to disable any unused board features or their

IRQ assignments.

140729 PRODUCT MANUAL PXM-C388-S 16

Watchdog Timer

The PXM-C388 features an advanced watchdog timer which can be used to guard against software lockups. Two

interfaces are provided to the watchdog timer. The Advanced interface is the most exible and recommended for new

designs. The other interface option is provided for software compatibility with older WinSystems single board computers.

Advanced

The watchdog timer can be enabled in the BIOS Settings by entering a value for Watchdog Timeout on the Intel → Super

I/O Control screen. Any non-zero value represents the number of minutes prior to reset during system boot. Once the

operating system is loaded, the watchdog can be disabled or recongured in the application software.

NOTE: It is recommended that a long timeout be used if the watchdog is enabled when trying to boot any operating

system.

The watchdog can be enabled, disabled or reset by writing the appropriate values to the conguration registers located

at I/O addresses 565h and 566h. The watchdog is enabled by writing a timeout value other than zero to the I/O address

566h and disabled by writing 00h to this I/O address. The watchdog timer is serviced by writing the desired timeout value

to I/O port 566h. If the watchdog has not been serviced within the allotted time, the circuit resets the CPU.

The timeout value can be set from 1 second to 255 minutes. If port 565h bit 7 equals 0, the timeout value written into I/O

address 566h is in minutes. The timeout value written to address 566h is in seconds if port 565 bit 7 equals 1.

Watchdog Timer Examples

Real-Time Clock/Calendar

A real-time clock is used as the AT-compatible clock/calendar. It supports a number of features including periodic and

alarm interrupt capabilities. In addition to the time and date keeping functions, the system conguration is kept in CMOS

RAM contained within the clock section. A battery must be enabled for the real-time clock to retain time and date during a

power down.

140729 PRODUCT MANUAL PXM-C388-S 18

The PXM-C388 supports either AT (standard power supply) or ATX type power supplies. Zero load supplies are

recommended. An AT power supply is a simple on/off supply with no interaction with the single board computer. Most

embedded systems use this type of power supply and it is the default setting. JP14 should always be jumpered with an

AT style power supply and +5V should be connected to both VCC and +5VSB (jumper JP15 on Rev. B and later).

ATX type power supplies function with a “soft” on/off power button and a +5 VSB (standby). If an ATX compatible power

supply is connected, JP14 and JP15 should be open and a power button (momentary contact) connected between pin 12

(power button) and pin 11 (ground) of J37. The +5 VSB signal provides the standby voltage to the PXM-C388 but does not

power any other features of the board. When the power button is pressed, the PXM-C388 pulls PSON (Power Supply On)

low and the power supply turns on all voltages to the single board computer. When the power button is pressed again,

the BIOS signals the event so ACPI-compliant operating systems can be shutdown before the power is turned off. In ATX

mode, if the power button is held for 4 seconds, the power supply is forced off, regardless of ACPI.

It is possible to use an ATX power supply without a power button. Simply jumper JP14 and it will boot when the supply is

turned on.

BATTERY BACKUP

An optional external battery, connected at J31, supplies the PXM-C388 board with standby power for the real-time

clock and CMOS setup RAM. An extended temperature lithium battery is available from WinSystems, part number

BAT-LTC-E-36-16-2 or BAT-LTC-E-36-27-2.

A power supervisory circuit contains the voltage sensing circuit and an internal power switch to route the battery

or standby voltage to the circuits selected for backup. The battery automatically switches ON when the VCC of the

systems drops below the battery voltage and back OFF again when VCC returns to normal.

WARNING: BAT-LTC-E-36-16-2 or BAT-LTC-E-36-27-2 must be connected at J31.

Improper installation of the battery could result in explosive failure. Please be careful

to note correct connection at location J31.

(For external battery. Provides battery backup to RTC and BIOS CMOS.)
