ATA5723/ATA5724/ATA5728
Use the function of the data clock only in conjunction with the bit check 3, 6 or 9 is recom-
mended. If the bit check is set to 0 or the receiver is set to receiving mode using the pin
POLLING/_ON, the data clock is available if the data clock control logic has detected the dis-
tance 2T (Start bit).
Note that for Bi-phase-coded signals, the data clock is issued at the end of the bit.
