3.2.2 System Protection Control Register
The system protection control register controls system monitor functions, software watchdog clock
prescaling, and bus monitor timing. This register can be written only once following power-on or 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
SWT[1:0] — Software Watchdog Timing
This field selects the divide ratio used to establish software watchdog time-out period. The following ta-
ble gives the ratio for each combination of SWP and SWT bits.
HME — Halt Monitor Enable
0 = Disable halt monitor function
1 = Enable halt monitor function
BME — Bus Monitor External Enable
0 = Disable bus monitor function for an internal to external bus cycle.
1 = Enable bus monitor function for an internal to external bus cycle.
BMT[1:0] — Bus Monitor Timing
This field selects a bus monitor time-out period as shown in the following table.
