Port A is disconnected from the internal signal path.*
Port A is connected to the BPG (back porch gate) signal.
Port A is connected to the SYG (sync tip gate) signal.
Port A is connected to the CBG (color burst gate) signal.
Port A is connected to the CBGW (color burst gate wide) signal. The CBGW is high
for the entire color burst period.
Port A is connected to the SLICE (mid way of the sync tip) signal.
Port A is connected to the VBI (vertical blanking interval) signal.
Port A is connect to the GPPORT bit.
Port A is configured as input. The input is connected directly to the signal path
selected by DATAA[2:0]. The internally generated gate signal is disconnected from
the signal path.*
Port A is an output and is driven by the internally generated signal as selected by
DATAA[2:0].
Port B is disconnected from the internal signal path.*
Port B is disconnected.
Port B is connected to the FH2 (twice per line pulses) signal.
Port B is connected to the FS_PULSE (falling edge of the sync tip) signal.
Port B is connected to the VBI_CVBS (VBI raw ADC) signal. This signal is high for
those lines that output data directly from the ADC (not YUV or RGB data).
Port B is connected to the VBI_PROC (VBI sliced) signal. This signal is high for
those video lines that output sliced VBI data.
Port B is connected to the COFF signal.
Port B is disconnected.
Port B is configured as input. The input is connected directly to the signal path
selected by DATAB[2:0]. The internally generated gate signal is disconnected from
the signal path.*
Port B is an output and is driven by the internally generated signal as selected by
DATAB[2:0].
