SarTxData0[17]: CRC10Stat
In normal SAR operation, when high, this bit indicates that the CRC10
polynomial check failed. This status is only valid when the cell in the buffer is
an OAM cell (as indicated by the cell header). This status should be ignored
for all other cell types.
In diagnostic read mode, class 3, this is the read data.
SarTxData0[31:18]: Unused
In normal SAR operation, not used.
In diagnostic read mode, class 3, this is the read data.
SarTxDataN[31:0], N=1..15:
In normal SAR operation, these registers contain the header and payload.
For Data stored in SarTxData14 & SarTxData15 are reserved and are not
used. A new transfer is initiated when SarTxData13 is read.
In diagnostic read mode, class 3, these registers are the read data. A new
transfer is initiated when SarTxData15 is read.
