Power-On Reset Operation
The CAT9532 incorporates Power-On Reset (POR)
circuitry which protects the internal logic against
powering up in the wrong state. The device is in a
reset state for V
threshold level (V
level, the reset state is released and the CAT9532
internal state machine and registers are initialized to
their default state.
