Some registers are unaffected by a Reset. Their status
is unknown on POR and unchanged by all other
Resets. All other registers are forced to a “Reset state”
depending on the type of Reset that occurred.
Most registers are not affected by a WDT wake-up,
since this is viewed as the resumption of normal
operation. Status bits from the RCON register, RI, TO,
PD, POR and BOR, are set or cleared differently in
different Reset situations, as indicated in
These bits are used by software to determine the
nature of the Reset.

Reset State of Registers
When the wake-up is due to an interrupt and the GIEH or GIEL bits are set, the PC is loaded with the
interrupt vector (008h or 0018h).
Reset state is ‘1’ for SBOREN and unchanged for all other Resets when software BOR is enabled
(BOREN<1:0> Configuration bits = 01). Otherwise, the Reset state is ‘0’.
