Figure 5. Oscillator Configuration
Power-On-Reset (POR). A timer circuit, clocked by a ded-
icated on-board RC oscillator, is used for the POWER-ON
RESET (POR) timer function. The POR time allows V&& and
the oscillator circuit to stabilize before instruction execution
begins.
The POR timer circuit is a one-shot timer triggered by one
of four conditions:
Power fail to Power OK status.
STOP-MODE RECOVERY (if bit D5 of SMR is set to 1).
WDT time-out.
The POR time is a specified as TPOR.
