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 Frequency

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–CCD00)
(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 70 shows how the
high and low bytes are set up in the registers.

NTSC PEDESTAL/PAL TELETEXT CONTROL
REGISTERS 3–0
(PCE15–0, PCO15–0)/(TXE15–0, TXO15–0)
(Subaddress (SR4–SR0) = 15–18H)
These 8-bit-wide registers are used to enable the NTSC pedes-
tal/PAL Teletext on a line by line basis in the vertical blanking
interval for both odd and even elds. Figures 68 and 69 show
the four control registers. A Logic 1 in any of the bits of these
registers has the effect of turning the Pedestal OFF on the
equivalent line when used in NTSC. A Logic 1 in any of the
bits of these registers has the effect of turning Teletext ON on
the equivalent line when used in PAL.
