SUBCARRIER FREQUENCY REGISTERS 3–0
(FSC31–FSC0) (Address (SR4–SR0) = 0CH–0FH)
These 8-bit-wide registers are used to set up the Subcarrier Fre-
quency. The value of these registers are calculated by using the
following equation:

SUBCARRIER PHASE REGISTER (FPH7–FPH0)
(Address (SR4–SR0) = 10H)
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 00Hex.

CLOSED CAPTIONING EVEN FIELD
DATA REGISTER 1–0 (CCD15–CCD0)
(Address (SR4–SR0) = 11–12H)
These 8-bit-wide registers are used to set up the closed captioning
extended data bytes on Even Fields. Figure 64 shows how the
high and low bytes are set up in the registers.
