port 3 mode selection; pin PORT3
TAGC IF input selection; feature enable set to enable (W8[7] = 1)
(W2[7] = 0)
output state; feature enable set to enable (W8[7] = 1); port 3 mode
selection set to logic output port (W8[5] = 1)
output state; feature enable set to enable (W8[7] = 1)
0 = fixed value

MODEP3
1 = feature PORT2; PORT3 monitor output of TAGC voltage and data
write register W11[7:0] enabled
0 = feature disabled; pin PORT2 and pin PORT3 set to high-ohmic;
data write register W11[7:0] = 0000 0000
1 = enabled
0 = disabled
1 = logic output port; level controlled by bit PORT3 (W8[2])
0 = monitor output of TAGC voltage
1 = IF3A and IF3B input
0 = IF1A and IF1B input or IF2A and IF2B input depends on VIF input
selection (W4[0])
1 = forced
0 = automatic; dependent on video level
1 = output port is HIGH (external pull-up resistor needed)
0 = output port is LOW
1 = output port is HIGH (external pull-up resistor needed)
0 = output port is LOW
