Watchdog timer

Watchdog timer expiration can be configured by host software to generate a host reset on the PG/RESET pin or a power cycle. When configured to issue a reset, nPM2100 is not reset internally.

A power cycle turns VOUT OFF for t_PWRDN and issues a reset through the PG/RESET pin. LDOSW is disabled and nPM2100 is reset internally.
