2.7 UART Interface
The CN68xx’s primary UART is connected to both a RS232 transceiver and an
RJ45 (for use with standard console cables) and a USB device port (type B - via a
USB-serial transceiver) on the front panel. Only one interface can be used at any
time.
The secondary UART is available for debug use.

5. Altera CPLD
The TAHOE 8622 board uses an Altera MAX II CPLD to allow the main CPU to control the basic
functionality of the board.
Some of the features controlled by the CPLD are: Power Sequencing, I2C, FAN and LED control.
Figure 14, TAHOE 8622 CPLD Functional Diagram
5.1 Power Sequencing Control
CPLD enables over time the various voltage regulators to meet the voltage
Turn-On requirements for various IC. During this process, it checks the various Power-
Good indication signals before enabling the next voltages in the sequence.
