Notes : 4. With Register 07 at Byte x0xxxxxx (Vertical S-Correction Control) then the S correction is inhibited, consequently the sawtooth has
a linear shape.
5. With Register 08 at Byte x0xxxxxx (Vertical C - Correction Control) then the C correction is inhibited, consequently the sawtooth
has a linear shape.
6. It is the frequency range for which the VERTICAL OSCILLATOR will automatically synchronize, using a single capacitor value on
Pin 22 and with a constant ramp amplitude.
