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.
