NOTES: 1. C0 and FL: Low Order Bits and C1 and FM: High Order Bits.
2. VDM0–2: Video Mod Depth control bits (for MC44355 VMD0–2 are Don’t Care).
3. SFD0–1: Sound subcarrier frequency control bits.
4. TB0–2 and X1, X0: Test modes bits, see table entitled TEST MODES.
5. AMD0–2: Audio Modulation Sensitivity, see table entitled AUDIO MODULATION SENSITIVITY (for MC44355 AMD0–2 are Don’t Care).
6. PSD0–2: Picture to Sound carrier ratio, see table entitled PICTURE to SOUND CARRIER RATIO (for MC44355 PSD0–1 are Don’t Care).
7. SysL: System L enable (selects AM sound and positive video modulation, MC44353 only).
8. TPEN: Test pattern enable (picture and sound).
9. N0 to N11: UHF frequency programming bits, in steps of 250 kHz.
