RESET
There are four kinds of resets: external reset, power-on reset,
watchdog reset, and software reset. The RSTSTA register
indicates the source of the last reset and can be written by user
code to initiate a software reset event.
The bits in this register can be cleared to 0 by writing to the
RSTCLR MMR at 0xFFFF0234. The bit designations in
RSTCLR mirror those of RSTSTA. These registers can be used
during a reset exception service routine to identify the source of
the reset. The implications of all four kinds of reset events are
tabulated in Table 30.
RSTSTA Register
Name:
RSTSTA
Address:
0xFFFF0230
Default value: Depends on type of reset
Access:
Read and write
Function:
This 8-bit register indicates the source of the
last reset event and can be written by user code
to initiate a software reset.
RSTCLR Register
Name:
RSTCLR
Address:
0xFFFF0234
Access:
Write only
Function:
This 8-bit write only register clears the corres-
ponding bit in RSTSTA.

Bit
Description
7:4
Not used. These bits are not used and always
read as 0.
3
External reset.
Automatically set to 1 when an external reset
occurs.
This bit is cleared by setting the corresponding bit
in RSTCLR.
2
Software reset.
This bit is set to 1 by user code to generate a soft-
ware reset.
This bit is cleared by setting the corresponding bit
in RSTCLR.1
1
Watchdog timeout.
Automatically set to 1 when a watchdog timeout
occurs.
Cleared by setting the corresponding bit in RSTCLR.
0
Power-on reset.
Automatically set when a power-on reset occurs.
Cleared by setting the corresponding bit in RSTCLR.
1
If the software reset bit in RSTSTA is set, any write to RSTCLR that does not
clear this bit generates a software reset.
