System Configuration and Protection
6.2.2.3.2
The SWSR is the location to which the SWT servicing sequence is written. To prevent SWT time-out, a
0x556C followed by 0xAA39 should be written to this register. The SWSR can be written at any time but
returns all zeros when read.

Software watchdog timer count. This field contains the count value of the software watchdog
timer.
Bus monitor timing. This field specifies the time-out period, in eight-system-clock resolution, of
the bus monitor. BMT must be set to non zero even if the bus monitor is not enabled.

Software watchdog freeze
0 Software watchdog continues to run while FREEZE is asserted
1 Software watchdog stops while FREEZE is asserted
Software watchdog enable. Software should clear this bit after a system reset to disable the
software watchdog timer.
0 Watchdog is disabled
1 Watchdog is enabled
Software watchdog reset/interrupt select
0 Software watchdog time-out causes a non-maskable interrupt to the RCPU
1 Software watchdog time-out causes a system reset
Software watchdog prescale
0 Software watchdog timer is not prescaled
1 Software watchdog timer is prescaled by 2048
