Notes :
5.
These parametersare not testedon each unit. They are measured during our internal qualification.
10. With Register 07 at Byte x0xxxxxx (S correctionis inhibited)and withRegister 08 at Bytex0xxxxxx (C correction is inhibited),the
sawtooth has a linear shape.
11. This is the frequencyrangefor which thevertical oscillatorwill automaticallysynchronize,using a single capacitorvalue on Pin22
and with a constant ramp amplitude.
12. TV is the vertical period.
