Reset State of Registers
Most registers are unaffected by a Reset. Their status
is unknown on POR and unchanged by all other
Resets. The 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 (CM, RI,
TO, PD, POR and BOR) are set or cleared differently in
different Reset situations, as indicated in Table 5-1.
These bits are used in software to determine the nature
of the Reset.
Table 5-2 describes the Reset states for all of the
Special Function Registers. These are categorized by
POR and BOR, MCLR and WDT Resets, and WDT
wake-ups.
