Notes : 5. These parameters are not tested on each unit. They are measured during our internal qualification.
10. With Register 07 at Byte x0xxxxxx (S correction is inhibited) and with Register 08 at Byte x0xxxxxx (C correction is inhibited), the
sawtooth has a linear shape.
11. This 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.
12. TV is the vertical period.
