COM Express Interfaces

The following applies to Figure 43 above.

The JTAG header may be used to program the PLD in-circuit.

The LPC bus is the interface to the Module host system.

Two seven-segment LED displays show the Port 80 POST (Power On Self Test) codes.

PLD outputs drive the LEDs.

On some systems, a BIOS setting is needed to allow POST codes to be forwarded to the LPC

bus.

Warning: Note that the pins on this particular CPLD are 5V tolerant and some of the pins

are subjected to voltages near 5V through the 7 segment LED.
