The OPEN Alliance SPI protocol defines two types of transactions:

data transactions for Ethernet frame transfers and control transac-

tions for register read/write operations.

A chunk is the basic element of data transactions, and they are

composed of 4 bytes of overhead plus the configured payload size.

Data transactions consist of an equal number of transmit and

receive chunks. Chunks in both transmit and receive directions

may or may not contain valid frame data independent from each

other, allowing for the simultaneous transmission and reception of

different length frames. The data header of the chunk in transmit

frames, and the data footer in receive frames, indicate which bytes

of the payload contain valid frame data. For full information on the

OPEN Alliance SPI protocol used by the ADIN1110, refer to OPEN

Alliance 10BASE-T1x MAC-PHY Serial Interface v1.0.

Note that CS has to be deasserted between data transactions and

control transactions, as shown in Figure 22.
