SUBCARRIER PHASE REGISTER
Bits:
FP7–FP0
Address:
SR4–SR0 = 0DH
This 8-bit-wide register is used to set up the subcarrier phase. Each bit represents 1.41°. For normal operation, this register is set to 00H.
CLOSED CAPTIONING EVEN FIELD DATA REGISTERS 1–0
Bits:
CED15–CED0
Address:
SR4–SR0 = 0EH–0FH
These 8-bit-wide registers are used to set up the closed captioning extended data bytes on even fields. Figure 46 shows how the high and
low bytes are set up in the registers.
