tRSTnAS

RSTn assertion time (2)

1. WAKEUPn has no debounce filter. PMIC detects a pulse smaller than tWAKEUPnAS duration. PMIC must detect a pulse equal to or longer

than tWAKEUPnAS duration.

2. RSTn has no debounce filter. PMIC detects a pulse smaller than tRSTnAS duration. PMIC must detect a pulse equal to or longer than tRSTnAS

duration.
