9.9 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 V_DD 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.
