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 = 2
0 = COP timeout period = 2
1 = COP module disabled
0 = COP module enabled
