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. STPMIC25 Electrical and timing characteristics DS14278 - Rev 3 page 11/145 |
