Read Transactions (82574 to MC)
This section details the pass-through read transactions that the MC can send to the
82574 over the SMBus.
SMBus read transactions lists the different SMBus read transactions supported by the
82574. All the read transactions are compatible with SMBus read block protocol format.
SMBus Read Transactions
1. The last fragment of the receive TCO packet is the packet status.
0xC0 or 0xD0 commands are used for more than one payload. If MC issues these read
commands, and the 82574 has no pending data to transfer, it always returns as default
opcode 0xDD with the 82574 status and does not NACK the transaction.
