Reset Operation
There are four kinds of reset: external, power-on, watchdog
expiration, 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.

Description
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.
Read-only bit. Indicates the size of the SRAM
memory available. If this bit is set, only 4 kB of
SRAM is available.
Reserved.
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.
