D7-D5. These bits are not used.

VSYNC. This bit reads the status of the VSYNC

pin. It is inverted with respect to the pin.

HSYNC. This bit reads the status of the HSYNC

latch. If a signal has been latched this bit will be

high.

AD2-AD0. These bits store the real time conver-

sion of the value present on the AD input pin. Un-

defined reset value.

D7, D6, D5, D4, D3. These bits are not used.

A/D Shift. This bit determines the voltage range of

the AFC input. Writing a zero will select the 0.5V to

4.5V range. Writing a one will select the 1.0V to

5.0V range. Undefined after reset.

O1,O0. These bits control the output pins O1,O0.

They are undefined after reset.
