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. TDA9110 8/29 |
