Reset Operation
There are four kinds of reset: external, power-on, watchdog
expiation, and software force. The RSTSTA register indicates
the source of the last reset, and RSTCLR allows clearing of the
RSTSTA register. These registers can be used during a reset
exception service routine to identify the source of the reset.
If RSTSTA is null, the reset is external.

Bit
Name
Description
4
Read-Only Bit. Indicates the size of the
Flash/EE memory available. If this bit is set,
only 32 kB of Flash/EE memory is available.
3
Read-Only Bit. Indicates the size of the SRAM
memory available. If this bit is set, only 4 kB of
SRAM is available.
2:1

0
Remap
Remap Bit. Set by user to remap the SRAM to
Address 0x00000000. Cleared automatically
after reset to remap the Flash/EE memory to
Address 0x00000000.

2
Software Reset. Set by user to force a software reset.
Cleared by setting the corresponding bit in RSTCLR.
1
Watchdog Timeout. Set automatically when a
watchdog timeout occurs. Cleared by setting the
corresponding bit in RSTCLR.
0
Power-On Reset. Set automatically when a power-on
reset occurs. Cleared by setting the corresponding bit in
RSTCLR.
