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.

The PMMR0, and PMMR2 register bits are cleared to zero following power up.
***
Subsequent reset pulses will not clear the registers.
