CGMS_WSS REGISTER 1 C/W1 (C/W17–C/W10)
(Address (SR4–SR0) = 1AH)
CGMS_WSS register 1 is an 8-bit-wide register. Figure 76 shows
the operations under control of this register.
C/W1 BIT DESCRIPTION
CGMS/WSS Data (C/W10–C/W15)
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 (C/W16–C/W17)
These bits are CGMS data bits only.

CGMS_WSS Register 2 is an 8-bit-wide register. Figure 77 shows
the operations under control of this register.
C/W2 BIT DESCRIPTION
CGMS/WSS Data (C/W20–C/W27)
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.

CONTRAST CONTROL REGISTER (CC00–CC07)
(Address (SR4–SR0) = 1DH)
The contrast control register is an 8-bit-wide register used to
scale the Y output levels. Figure 78 shows the operation under
control of this register.
Y Scale Value (CC00–CC07)
These eight bits represent the value required to scale the Y pixel
data from 0.0 to 1.5 of its initial level. The value of these eight
bits is calculated using the following equation:
Y Scale Value
=
Scale Factor
×
128
Example:
Scale Factor = 1.18
Y Scale Value = 1.18
×
128 = 151.04
Y Scale Value = 151 (rounded to the nearest integer)
Y Scale Value = 10010111

COLOR CONTROL REGISTERS 1–2 (CC10–CC27)
(Address (SR4–SR0) = 1EH–1FH)
The color control registers are 8-bit-wide registers used to scale
the U and V output levels. Figure 79 shows the operations under
control of these registers.
CC1 BIT DESCRIPTION
U Scale Value (CC10–CC17)
These eight bits represent the value required to scale the U level
from 0.0 to 2.0 of its initial level. The value of these eight bits is
calculated using the following equation:
U Scale Value
=
Scale Factor
×
128
Example:
Scale Factor = 1.18
U Scale Value = 1.18

CC2 BIT DESCRIPTION
V Scale Value (CC20–CC27)
These eight bits represent the value required to scale the V pixel
data from 0.0 to 2.0 of its initial level. The value of these eight
bits is calculated using the following equation:
V Scale Value = Scale Factor
×
128
Example:
Scale Factor = 1.18
V Scale Value = 1.18
