15.4.4 Power-On Reset
The power-on reset (POR) circuit in the SIM clears the COP prescaler
4096 OSCXCLK cycles after power-up.
15.4.5 Internal Reset
An internal reset clears the SIM counter and the COP counter.
15.4.6 Reset Vector Fetch
A reset vector fetch occurs when the vector address appears on the data
bus. A reset vector fetch clears the COP prescaler.
