4–7 — Reserved, should be cleared.
8–15 Data Data field. Contains the monitor channel data byte that the SMC received.
29.5.6 SMC GCI Monitor Channel TxBD
The CP uses the GCI monitor channel TxBD, shown in
transmit byte. The TxBD itself contains the monitor data to be sent.

0 R Ready.
0 Cleared by the CP after transmission. The TxBD is now available to the core.
1 Set by the core when the data byte associated with this BD is ready for transmission.
1 L Last (EOM). When L = 1, the SMC first transmits the buffer data and then transmits the EOM
indication on the E bit.
2 AR Abort request. Set by the SMC when an abort request is received on the A bit. The transmitter sends
the EOM on the E bit after receiving an abort request.
3–7 — Reserved, should be cleared.
8–15 Data Data field. Contains the data to be sent by the SMC on the monitor channel.
29.5.7 SMC GCI C/I Channel RxBD
The GCI C/I channel RxBD, shown in
byte. The RxBD itself receives the C/I data.
