If a reset is caused by a power-fail, the power-fail moni-
tor can be set to one of the following intervals:
Always on—continuous monitoring
211 nanopower ring oscillator clocks (~256ms)
212 nanopower ring oscillator clocks (~512ms)
213 nanopower ring oscillator clocks (~1.024s)
In the case where the power-fail circuitry is periodically
turned on, the power-fail detection is turned on for two
nanopower ring oscillator cycles. If VDD > VRST during
detection, VDD is monitored for an additional nanopow-
er ring oscillator period. If VDD remains above VRST for
the third nanopower ring period, the CPU exits the reset
state and resumes normal operation from utility ROM at
8000h after satisfying the crystal warmup period.
If a reset is generated by any other event, such as the
RESET pin being driven low externally or the watchdog
timer, the power-fail, internal regulator, and crystal
remain on during the CPU reset. In these cases, the
CPU exits the reset state in less than 20 crystal cycles
after the reset source is removed.

On
Off
—
VDD < VPOR.
B
On
—
VPOR < VDD < VRST.
Crystal warmup time, tXTAL_RDY.
CPU held in reset.
C
On
—
VDD > VRST.
CPU normal operation.
D

—
VRST < VDD < VPFW.
PFI is set when VRST < VDD < VPFW and maintains
this state for at least tPFW, at which time a power-
fail interrupt is generated (if enabled).
CPU continues normal operation.

Yes
VPOR < VDD < VRST.
Power-fail detected.
CPU goes into reset.
Power-fail monitor turns on periodically.
