10.8 Power-Up Timer (PWRT)

The Power-up Timer provides up to a 64 ms time-out period on POR or BOR. The device is held in Reset as long as PWRT is active. The PWRT delay allows additional time for the VDD to rise to an acceptable level.

The Power-up Timer is controlled by the PWRTS bits. The Power-up Timer starts after the release of the POR and BOR. For additional information, refer to the following Microchip application note, available at the corporate website (www.microchip.com):
