9.1.2.6 The ZPLD Power Management
The ZPLD implements a Zero Power Mode, which provides considerable power savings
for low to medium frequency operations. To enable this feature, the ZPLD Turbo bit in the
Power Management Mode Register 0 (PMMR0) has to be turned off.
If none of the inputs to the ZPLD are switching for a time period of 70ns, the ZPLD puts
itself into Zero Power Mode and the current consumption is minimal. The ZPLD will resume
normal operation as soon as one or more of the inputs change state.
Two other features of the ZPLD provide additional power savings:
1. Clock Disable:
Users can disable the clock input to the ZPLD and/or macrocells,
thereby reducing AC power consumption.
2. Product Term Disable:
Unused product terms in the ZPLD are disabled by the PSDsoft Software automatically
for further power savings.
The ZPLD power configuration is described in the Power Management Unit section.
