PLD Array Addr:
In XA mode, A3-A0 come from PF3-PF0, and A7-A4 come from ADIO7-ADIO4).
PLD Array CNTL2:
PLD Array CNTL1
PLD Array CNTL0
PLD Array ALE
Bit 7
not used
(set to ’0’)
0: Automatic Power-down (APD) is disabled.
1: Automatic Power-down (APD) is enabled.
0: PLD Turbo is on.
1: PLD Turbo is off, saving power.
0: CLKIN to the PLD AND array is connected. Every CLKIN change powers up the PLD
when Turbo bit is off.
1: CLKIN to the PLD AND array is disconnected, saving power.
0: CLKIN to the PLD macrocells is connected.
1: CLKIN to the PLD macrocells is disconnected, saving power.
0: Address A7-A0 are connected to the PLD array.
1 Address A7-A0 are blocked from the PLD array, saving power.
0: CNTL2 input to the PLD AND array is connected.
1: CNTL2 input to the PLD AND array is disconnected, saving power.
0: CNTL1 input to the PLD AND array is connected.
1: CNTL1 input to the PLD AND array is disconnected, saving power.
0: CNTL0 input to the PLD AND array is connected.
1: CNTL0 input to the PLD AND array is disconnected, saving power.
0: ALE input to the PLD AND array is connected.
1: ALE input to the PLD AND array is disconnected, saving power.
