I-PORT SIGNAL DEFINITIONS
IGP0 is output field ID, as defined by OFIDC[90H[6]]
IGP0 is A/B task flag, as defined by CONLH[90H[7]]
IGP0 is sliced data flag, framing the sliced VBI-data at the I-port
IGP0 is set to logic 0 (default polarity)
IGP0 is the output FIFO almost filled flag
IGP0 is the output FIFO overflow flag
IGP0 is the output FIFO almost full flag, level to be programmed in subaddress 86H
IGP0 is the output FIFO almost empty flag, level to be programmed in subaddress 86H

X = don’t care.
I-PORT OUTPUT SIGNAL DEFINITIONS
IGPH is a H-gate signal, framing the scaler output
IGPH is an extended H-gate (framing H-gate during scaler output and scaler
input H-reference outside the scaler window)
IGPH is a horizontal trigger pulse, on active going edge of H-gate
IGPH is a horizontal trigger pulse, on active going edge of extended H-gate
IGPV is a V-gate signal, framing scaled output lines
IGPV is the V-reference signal from scaler input
IGPV is a vertical trigger pulse, derived from V-gate
IGPV is a vertical trigger pulse derived from input V-reference
