Bit 1 0 = Automatic Power Down (APD) is disabled.
1 = Automatic Power Down (APD) is enabled.
Bit 3 0 = PLD Turbo is on.
1 = PLD Turbo is off, saving power.
Bit 4 0 = CLKIN input to the PLD AND array is connected.
Every CLKIN change will power up the PLD when Turbo bit is off.
1 = CLKIN input to PLD AND array is disconnected, saving power.

***Bits 0, 2, 6, and 7 are not used, and should be set to 0, bit 5 should be set to 1.
***The PMMR0, and PMMR2 register bits are cleared to zero following power up.
***Subsequent reset pulses will not clear the registers.

Bit 0 0 = Address A[7:0] inputs to the PLD AND array are connected.
1 = Address A[7:0] inputs to the PLD AND array are disconnected, saving power.
Note: In 80C51XA mode, A[7:1] comes from Port F (PF1-PF3) and AD10 [3:0].
Bit 2 0 = Cntl0 input to the PLD AND array is connected.
1 = Cntl0 input to PLD AND array is disconnected, saving power.
Bit 3 0 = Cntl1 input to the PLD AND array is connected.
1 = Cntl1 input to PLD AND array is disconnected, saving power.
Bit 4 0 = Cntl2 input to the PLD AND array is connected.
1 = Cntl2 input to PLD AND array is disconnected, saving power.
Bit 5 0 = ALE input to the PLD AND array is connected.
1 = ALE input to PLD AND array is disconnected, saving power.
Bit 6 0 = WRH/DBE input to the PLD AND array is connected.
1 = WRH/DBE input to PLD AND array is disconnected, saving power.
**Unused bits should be set to 0.
**Refer to Table 14 the signals that are blocked on pins CNTL0-2.
