Figure 8 System Protection Block
The system protection control register controls system monitor functions, software watchdog clock
prescaling, and bus monitor timing. This register can only be written once following reset, but can
be read at any time.
SWE — Software Watchdog Enable
0 = Software watchdog disabled
1 = Software watchdog enabled
SWP — Software Watchdog Prescale
This bit controls the value of the software watchdog prescaler.
0 = Software watchdog clock not prescaled
1 = Software watchdog clock prescaled by 512
The reset value of SWP is the complement of the state of the MODCLK pin during reset.
