The following equation calculates the timeout period for a slow reference frequency,
where f
The following equation calculates the timeout period for a fast reference frequency.
The following equation calculates the timeout period for an externally input clock
frequency on both slow and fast reference frequency devices, when f
system clock frequency.
This field selects the bus monitor timeout period. Refer to Table D-7.
0 = Halt monitor is disabled.
1 = Halt monitor is enabled.
0 = Disable bus monitor for external bus cycles.
1 = Enable bus monitor for external bus cycles.
