Section 8
Programmable Logic Device
The Pm8560 uses a Programmable Logic Device (PLD) to provide control logic for the local
bus. The PLD implements various registers for product identification, board configuration,
reset, clocking, and Serial Presence Detect (SPD)
.
This chapter describes the PLD registers
on the Pm8560.
PLD REGISTER SUMMARY
The PLD registers start at address E808,0000
16
. As a rule, registers retain their values
through all resets except for power-on and front panel reset.
Table 8-1
lists the 8-bit PLD reg-
isters followed by the register bit descriptions.
