State Data A9: 1 to 4 (MOD)
Determines the luminance signal black level and the chroma signal burst level. These four data items
determine the (R-Y) burst level for PAL format TV signals.

• State data A9 (1 to 4): Encoder (MOD) control characteristics
1: Setup
(D7 × 2⁶ + D6 × 2⁵ + D5 × 2⁴ + D4 × 2³ + D3 × 2² + D2 × 2¹ + D1) × 2/256
2: Pedestal
D7 × 2⁶ + D6 × 2⁵ + D5 × 2⁴ + D4 × 2³ + D3 × 2² + D2 × 2¹ + D1/256
Note: However, when the A9 to A2 D8 bit (delay) is set to 1, the Y data is delayed by one fs clock
cycle.
3: Burst level (B-Y)
D7 × 2⁶ + D6 × 2⁵ + D5 × 2⁴ + D4 × 2³ + D3 × 2² + D2 × 2¹ + D1/256
4: Burst level (R-Y)
• Used in PAL mode
• In NTSC mode, used for phase adjustment
