Command 9 identification code
If VS is the vertical display start position then:
VS = H
Where H is horizontal period pulse period.
If VS is the horizontal display start position then:
HS = Tc
Where Tc is a single period of the LC oscillator connected to pins
2 and 3 (OSC
Tc is the period of the input clock (4fsc input) if CTRL1 (pin 4) is
high.
NTSC mode: 7.159 MHz = 4fsc
PAL mode: 7.094 MHz = 4fsc
