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) 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 EPX-C380.

IRQ0 18.2 Hz heartbeat

IRQ8 Real Time Clock

IRQ9 FREE **

IRQ10 Digital I/O

IRQ11 PCIe Interrupts

IRQ12 Mouse

IRQ13 Floating point processor

IRQ14 IDE

IRQ15 PCIe Interrupts

*

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.

Preliminary

110502 PRODUCT MANUAL EPX-C380 17

Watchdog Timer

The EPX-C380 features an advanced watchdog timer which can be used to guard against software lockups. Three

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

designs. The other two interface options are 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.

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.

Preliminary

110502 PRODUCT MANUAL EPX-C380 20

The EPX-C380 supports either AT (standard power supply) or ATX type power supplies. Zero load supplies are

recommended. JP2 species the style of supply connected to the single board computer (SBC). 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.

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, JP2 should be set accordingly and a power button (momentary contact) connected between pin 3

(power button) and pin 2 (ground) of J8. The +5 VSB signal provides the standby voltage to the EPX-C380 but does not

power any other features of the board. When the power button is pressed, the EPX-C380 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. Since this is software

driven, it is possible that a software lockup could prevent the power button from functioning properly. For the BIOS to

report the ATX supply to ACPI-compatible operating systems, JP2 must be setup correctly.
