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
page 197).
The COPL signal reflects the state of the COP rate select bit. (COPL) in
the configuration register. (See
page 197).
