†† Reset by POR only.
Address:
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
CONFIG1 register. (See
Registers
The COPRS signal reflects the state of the COP rate select bit (COPRS)
in the CONFIG1 register.
COPRS — COP Rate Select
COPD — COP Disable Bit

Read:
Write:
COPRS selects the COP time-out period. Reset clears COPRS.
COPD disables the COP module.
1 = COP time out period = 2
0 = COP time out period = 2
1 = COP module disabled
0 = COP module enabled
