Read Transactions (82574L to MC)
This section details the pass-through read transactions that the MC can send to the
82574L over the SMBus.
SMBus read transactions lists the different SMBus read transactions supported by the
82574L. 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 82574L has no pending data to transfer, it always returns as
default opcode 0xDD with the 82574L status and does not NACK the transaction.
