Writing any value to the COP control register (COPCTL) (see
Control Register
stages 12 through 4 of the COP prescaler. Reading the COP control
register returns the reset vector.
The power-on reset (POR) circuit clears the COP prescaler 4096
CGMXCLK cycles after power-up.
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. (See
(CONFIG-1)).
The COPRS signal reflects the state of the COP rate select bit. (COPRS)
in the configuration register. (See
(CONFIG-1)).
