Timings Control
All timings are controlled by a master oscillator that can be internal or externally provided. At
power up, OSC will default to the internal 4MHz oscillator. Setting W2 bits 9 and 10 will
select the external oscillator frequency or it's dividing by either 2 or 4.
The switching blanking time for masking transient can be selected by W2 bits 7 and 8.
