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 71 shows how the
high and low bytes are set up in the registers.

(Subaddress (SR4–SR0) = 15–18H)
These 8-bit-wide registers are used to enable the NTSC pedestal/
PAL Teletext on a line-by-line basis in the vertical blanking
interval for both odd and even
fi
elds. Figures 73 and 74 show
