Power-up Timer (PWRT)

The Power-up Timer provides a nominal 66 ms (2048 cycles of LFINTOSC) time out on POR or Brown-out Reset.

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 enabled by clearing the PWRTE bit in Configuration Words.

The Power-up Timer starts after the release of the POR and BOR.

For additional information, refer to Application Note AN607, “Power-up Trouble Shooting” (DS00000607).
