Configuration Register/AD9805
T he Configuration Register controls three functions: a color
pointer, gain and offset pin configurations, and digital gain
scaling. Figure 6 shows the AD9805 Configuration Register.
Bits 0–2 control the digital scaling function. Setting a Bit
makes the corresponding condition true. Resetting Bits 0–2
disables and bypasses the digital multiplier. Bits 3–5 control
the gain and offset pin distribution. Resetting Bits 3–5 disables
and bypasses the digital subtracter and sets the gain word width
to 10. Setting any bit makes the corresponding condition true.
If Bit 3 is set, the 2 LSBs of the gain word become the 2 MSBs
of the offset word. If Bit 4 is set, the LSB of the gain word
becomes MSB of the offset word. Bits 6 and 7 direct register
data written to the MPU<7:0> bus to the appropriate red,
green or blue register.

MPU Port Map
T able II shows the MPU Port Map. T he MPU Port Map is
accessed through pins A0, A1 and A2 of the AD9807/AD9805,
and provides the decoding scheme for the various registers of
the AD9807/AD9805. When writing or reading from any of the
registers, the appropriate bits must be applied to A0–A2.

Configuration Register/AD9807
T he Configuration Register controls three functions: a color
pointer, gain and offset pin configurations, and digital gain
scaling. Figure 5 shows the AD9807 Configuration Register.
Bits 0–2 control the digital scaling function. Setting a bit makes
the corresponding condition true. Resetting Bits 0–2 disables
and bypasses the digital multiplier. Bits 3–5 control the gain
and offset pin distribution. Resetting Bits 3–5 disables and
bypasses the digital subtracter and sets the gain word width to
12. Setting any bit makes the corresponding condition true. For
example, if Bit 3 is set, the 2 LSBs of the gain word become the
2 MSBs of the offset word. If Bit 4 is set, the LSB of the gain
word becomes MSB of the offset word. Bits 6 and 7 direct
register data written to the MPU<7:0> bus to the appropriate
red, green or blue register.
