* LVIDR, LVI5OR3, URSTD, and LVID, are reset by POR or LVI reset 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
CONFIG register. (See
The COPRS signal reflects the state of the COP rate select bit (COPRS)
in the CONFIG register. (See
