Technical Data
Writing any value to the COP control register (COPCTL) (see
Control
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 COPL signal reflects the state of the COP rate select bit (COPL) in
the configuration register. See
(CONFIG-1).
