9.6. Determining the Source of the Last Reset
The RSTSTA register can be used to determine the cause of the last reset. Note: If the PORSI bit is set to logic 1,
all other bits in RSTSTA are undefined. It is impossible to differentiate between a power-on, power-fail, and
oscillator-fail reset by reading the RSTSTA register.
Bits 7–3: UNUSED. Read = 00000b, Write = don’t care.

0: Source of last reset was not a power-on, power-fail, or oscillator-fail event.
1: Source of last reset was a power-on, power-fail, or oscillator-fail event.
PINRSI: External Pin Reset Indicator
0: Source of last reset was not the /RST pin.
