Table 9. Denition of Status Bits of MRWDxx that Vary for Different Channels for the ORT42G5
In the ORT42G5, SYNC2_[A, B]_OOS and SYNC4_OOS signals can be used with CH24_SYNC_xx to determine
if the desired multi-channel alignment was successful. If, when CH24_SYNC_xx goes high with the corresponding
OOS signal remaining low, the data being transferred across the core/FPGA interface is correctly aligned between
channels. Note that only the signals corresponding to the selected alignment mode will be meaningful.
