Input Control Signals
The PSD provides the option to turn off the input
control signals (CNTL0, CNTL1, CNTL2, ALE, and
DBE) to the PLD to save AC power consumption.
These control signals are inputs to the PLD AND
array.

Not Counting
During Power Down Mode, or, if any of them are
not being used as part of the PLD logic equation,
these control signals should be disabled to save
AC power. They will be disconnected from the
PLD AND array by setting bits 2, 3, 4, 5, and 6 to
a ‘1’ in the PMMR2.
