Table 23. PMMR0 Register
Note: The bits of this register are cleared to zero following power-up. Subsequent Reset (RESET) pulses do not clear the registers.
Table 24. PMMR2 Register
Note: For Bit 4, Bit 3, Bit 2: See Table 34, page 47 for the signals that are blocked on pins CNTL0-CNTL2.
Table 25. VM Register
Note: On RESET, Bits 1-4 are loaded to configurations that are selected by the user in PSDsoft. Bit 0 and Bit 7 are always cleared on RESET.
This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.

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.
Note: In X A Mode, A3-A0 come from PF3-PF0, and A7-A4 come from ADIO7-ADIO4.
1 = CNTL2 input to the PLD AND array is disconnected, saving power.
1 = CNTL1 input to the PLD AND array is disconnected, saving power.
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.
0 = WRH/DBE input to the PLD AND array is connected.
1 = WRH/DBE input to the PLD AND array is disconnected, saving power.
0 = PSEN cannot access SRAM in 80C51XA modes.
1 = PSEN can access SRAM in 80C51XA modes.
0 = PSEN cannot access Secondary NVM in 80C51XA modes.
1 = PSEN can access Secondary NVM in 80C51XA modes.
0 = PSEN cannot access Primary Flash memory in 80C51XA modes.
1 = PSEN can access Primary Flash memory in 80C51XA modes.
0 = RD cannot access Secondary NVM in 80C51XA modes.
1 = RD can access Secondary NVM in 80C51XA modes.
0 = RD cannot access Primary Flash memory in 80C51XA modes.
1 = RD can access Primary Flash memory in 80C51XA modes.
0 = Peripheral mode of Port F is disabled.
1 = Peripheral mode of Port F is enabled.
