5.5.2 COP Control Register
The COP control register (COPCR), shown in Figure 5-5, performs
these functions:
Enables clock monitor function
Enables COP function
Selects timeout duration of COP timer
And flags these conditions:
COP timeout
Clock monitor reset
COPF — Computer Operating Properly Flag
Reading the COP control register clears COPF.
1 = COP or clock monitor reset has occurred.
0 = No COP or clock monitor reset has occurred.
CME — Clock Monitor Enable Bit
This bit is readable any time, but may be written only once.
1 = Clock monitor enabled
0 = Clock monitor disabled
