Table 19 SAV/EAV codes on I port
Notes
1. The leading byte sequence is: FFH-00H-00H.
2. The MSB of the SAV/EAV code byte is controlled by:
a) Scaler output data: task A
MSB = CONLH[90H[7]]; task B MSB = CONLH[C0H[7]].
b) VBI data slicer output data: DID[5:0] 5DH[5:0] = 3EH
MSB = 1; DID[5:0] 5DH[5:0] = 3FH MSB = 0.
