Indicates lock type. This signal provides additional
information about the atomic characteristics of the read
transfer.
00: Normal access
01: Exclusive access
10: Locked access
11: Reserved
Indicates response ID. The identification tag of the write
response. The MDDR_SMC_AXI_M_BID value must
match the MDDR_SMC_AXI_M_AWID value of the
write transaction to which the slave is responding.
Read ID tag. This signal is the ID tag of the read data
group of signals. The MDDR_SMC_AXI_M_RID value
is generated by the slave and must match the
MDDR_SMC_AXI_M_ARID value of the read
transaction to which it is responding.
Indicates read response. This signal indicates the
status of the read transfer.
00: Normal access okay
01: Exclusive access okay
10: Slave error
11: Decode error
Indicates write response. This signal indicates the
status of the write transaction.
00: Normal access okay
01: Exclusive access okay
10: Slave error
11: Decode error
Indicates read data.
Indicates that the current master is performing a locked
sequence of transfers.
Indicates write control signal. When High, this signal
indicates a write transfer, and when Low, a read
transfer.
The transfer response indicates the status of transfer.
When High, the signal indicates that a transfer has
been completed on the bus. This signal may be driven
Low to extend a transfer.
Indicates the burst type.
Indicates the type of the current transfer.
00: Idle
01: Busy
10: Non-sequential
11: Sequential
