Offset C18h-C1Bh
This register describes two closed captioning characters that are encoded onto the line programmed by CC_LINE (F4BAR0+Memory
Offset C28h[4:0]) of the odd video field. These characters are encoded onto the video output only once. The characters written must
have an odd parity MSB bit. If characters 1 and 2 are not updated before the next VSYNC at the start of a top field, NULL (0) characters
are encoded onto the line. Normally, closed captioning data is place on line 21 (CC_LINE = 11h) for NTSC operation.
Offset C1Ch-C1Fh
This register describes two extended data services characters that are encoded onto the line programmed by CC_LINE (F4BAR0+Mem-
ory Offset C28h[4:0]) of the even video field. These characters are encoded onto the video output only once. The characters written
must have an odd parity MSB bit. If characters 1 and 2 are not updated before the next VSYNC at the start of a bottom field, NULL (0)
characters are encoded onto the line. Normally, extended data services data is place on line 21 (CC_LINE = 11h) for NTSC operation.

Description
Reserved.
DISPWIDTH (Display Width). Defines the width of the displayed video in 13.5 MHz clock periods.
If “Frame_Width” is the displayed frame width in pixels, the number programmed is Frame_Width − 1.
For standard NTSC and PAL applications, the number programmed is 719 (2CFh).
Reserved.
CHAR2 (Second Closed Caption Character).
CHAR1 (First Closed Caption Character).
Reserved.
CHAR2 (Second Extended Data Services Character).
CHAR1 (First Extended Data Services Character).
Reserved.
CGMS_DATA (CGMS Data). This bit field contains the NTSC (JAPAN) CGMS data. This data in this field is modulated onto
the video signal on the field line specified in the CGMS_LINE bits of Closed Captioning Control register (F4BAR0+Memory
Offset C28h[12:8]). The data is modulated on to the specified line in the top and/or bottom field according to the setting of
bits [14:13] in the Closed Captioning Control register. The bits are modulated onto the video waveform in the order 19-0.
Reserved.
WSS_DATA (Wide Screen Signalling Data). This register contains PAL “Wide Screen Signalling” data. The data in this
field is modulated onto line 23 of PAL frames if bit 15 (WSE) of the Closed Captioning Control register is set to 1
(F4BAR0+Memory Offset C28h[15] = 1). The bits are modulated onto the video waveform in the order 0-13.
Reserved.
WSE (Wide Screen Signalling Enable). If this bit is asserted, and the encoder is in PAL mode, the contents of the WSS
Data register (F4BAR0+Memory Offset C24h[13:0]) are encoded onto line 23 of the bottom video field.
CTE (CGMS Odd Field Enable). If this bit is asserted, the contents of the CGMS Data register (F4BAR0+Memory Offset
C20h[19:0]) are encoded in the odd field onto the line set in GCMS_LINE (bits [12:8]).
CBE (CGMS Even Field Enable). If this bit is asserted, the contents of the CGMS Data register are encoded in the even
field onto the line set in GCMS_LINE (bits [12:8]).
CGMS_LINE (CGMS Line). This bit field selects the line on which CGMS Data should be encoded. programmed with “line
number minus 4”. Normally set to 16 NTSC operation.
Reserved. Must be set to 0.
CCE (Closed Captioning Enable). If this bit is asserted, the contents of the Closed Captioning Data register
(F4BAR0+Memory Offset C18h[15:0]) are encoded in the odd field onto the line set in CC_LINE (bits [4:0]).
EDSE (Extended Data Services Enable). If this bit is asserted, the contents of the Extended Data Services Data register
(F4BAR0+Memory Offset C1Ch[15:0]) are encoded in the even field onto the line set in CC_LINE (bits [4:0]).
CC_LINE (Closed Captioning Line). This bit field selects the line on which Closed Captioning and/or Extended Data Ser-
vices Data should be to encoded, programmed with the “line number minus 4”. Normally set to 17 for NTSC operation.
