Address:
Reset:
An internal reset clears the COP prescaler and the COP counter.
A reset vector fetch occurs when the vector address appears on the data
bus. A reset vector fetch clears the COP prescaler.
The COPD signal reflects the state of the COP disable bit (COPD) in the
configuration register 1. (See
The COPRS signal reflects the state of the COP rate select bit (COPRS)
in the configuration register 1. (See
COPRS — COP Rate Select Bit
COPD — COP Disable Bit
Read:
Write:
COPRS selects the COP timeout period. Reset clears COPRS.
COPD disables the COP module.
1 = COP timeout period is 2
0 = COP timeout period is 2
1 = COP module disabled
0 = COP module enabled
