CGMS and WSS
The CGMS and WSS data packets convey the same type of
information for different video standards. WSS is for PAL and
CGMS is for NTSC; therefore, the CGMS and WSS readback
registers are shared. WSS is biphase coded; the VDP performs a
biphase decoding to produce the 14 raw WSS bits in the CGMS/
WSS readback I2C registers and to set the CGMS_WSS_AVL bit.
CGMS_WSS_CLEAR, CGMS/WSS Clear, Address 0x78[2],
User Sub Map, Write Only, Self-Clearing
Setting CGMS_WSS_CLEAR to 1 reinitializes the CGMS/WSS
readback registers.
CGMS_WSS_AVL, CGMS/WSS Available, Address 0x78[2],
User Sub Map, Read Only
When CGMS_WSS_AVL is 0, CGMS/WSS is not detected.
When CGMS_WSS_AVL is 1, CGMS/WSS is detected.
VDP_CGMS_WSS_DATA_0[3:0], Address 0x7D[3:0];
VDP_CGMS_WSS_DATA_1[7:0], Address 0x7E[7:0];
VDP_CGMS_WSS_DATA_2[7:0], Address 0x7F[7:0];
User Sub Map, Read Only
These bits hold the decoded CGMS or WSS data.
Refer to Figure 48 and Figure 49 for the I2C-to-WSS and I2C-to-
CGMS bit mapping.
