C/W0 BIT DESCRIPTION
CGMS Data Bits (C/W03–C/W00)
These four data bits are the final four bits of CGMS data output
stream. Note it is CGMS data ONLY in these bit positions, i.e.,
WSS data does not share this location.
CGMS CRC Check Control (C/W04)
When this bit is enabled (“1”), the last six bits of the CGMS
data, i.e., the CRC check sequence, is calculated internally by
the ADV7170/ADV7171. If this bit is disabled (“0”) the CRC
values in the register are output to the CGMS data stream.
CGMS Odd Field Control (C/W05)
When this bit is set (“1”), CGMS is enabled for odd fields.
Note this is only valid in NTSC mode.
CGMS Even Field Control (C/W06)
When this bit is set (“1”), CGMS is enabled for even fields.
Note this is only valid in NTSC mode.
WSS Control (C/W07)
When this bit is set (“1”), wide screen signaling is enabled. Note
this is only valid in PAL mode.
CGMS_WSS REGISTER 1 C/W1 (C/W17–C/W10)
(Address [SR4–SR0] = 17H)
CGMS_WSS register 1 is an 8-bit-wide register. Figure 52
shows the operations under the control of this register.
C/W1 BIT DESCRIPTION
CGMS/WSS Data Bits (C/W15–C/W10)
These bit locations are shared by CGMS data and WSS data. In
NTSC mode these bits are CGMS data. In PAL mode these
bits are WSS data.
CGMS Data Bits (C/W17–C/W16)
These bits are CGMS data bits only.
CGMS_WSS REGISTER 2 C/W1 (C/W27–C/W20)
(Address [SR4–SR0] = 18H)
CGMS_WSS register 2 is an 8-bit-wide register. Figure 53
shows the operations under the control of this register.
C/W2 BIT DESCRIPTION
CGMS/WSS Data Bits (C/W27–C/W20)
These bit locations are shared by CGMS data and WSS data. In
NTSC mode these bits are CGMS data. In PAL mode these
bits are WSS data.
