Power management
The PSD Module offers configurable power saving options, and also a way to manage
power to the SRAM (battery backup). These options may be used individually or in
combinations. A top level description for these functions is given here, then more detailed
descriptions will follow.

OR ARRAY
Zero-Power Memory: All memory arrays (Flash and SRAM) in the PSD Module are
built with zero-power technology, which puts the memories into standby mode (~ zero
DC current) when 8032 address signals are not changing. As soon as a transition
occurs on any address input, the affected memory “wakes up”, changes and latches its
outputs, then goes back to standby. The designer does not have to do anything special
