ADuC7060/ADuC7061
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 inTable 30.

Description
Not used. These bits are not used and always
read as 0.
External reset.
Automatically set to 1 when an external reset
occurs.
This bit is cleared by setting the corresponding bit
in RSTCLR.
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.
Watchdog timeout.
Automatically set to 1 when a watchdog timeout
occurs.
Cleared by setting the corresponding bit in RSTCLR.
Power-on reset.
Automatically set when a power-on reset occurs.
Cleared by setting the corresponding bit in RSTCLR.
