5.6.2 C9A COP Control Register
The COP control register, shown in Figure 5-5, performs these
functions:
Enables clock monitor function
Enables MC68HC05C9A compatible COP function
Selects timeout duration of COP timer
and flags the following conditions:
A 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
COPE — COP Enable Bit
This bit is readable any time. COPE, CM1, and CM0 together may be
written with a single write, only once, after reset. This bit is cleared by
reset.
1 = COP enabled
0 = COP disabled
