CGMS_WSS REGISTER 1 C/W1 (C/W17 TO C/W10)
(Address [SR4 to 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 to 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 TO C/W16)
These bits are CGMS data bits only.
