PowerOn Reset Operation
When the power supply is applied to VCC pin, an internal
poweron reset pulse holds the CAT9554/9554A in a reset
state until VCC reaches VPOR level. At this point, the reset
condition is released and the internal state machine and the
CAT9554/9554A registers are initialized to their default
state.
