Read Transaction Protocol
Three main types of read transactions are used by this part: Read Byte, Read Word and Read Block. The command packet format for a read transaction is dependent on the specific transaction type, which varies with respect to each PMBus command. The appropriate read transaction type for each command is specified in its designated section within this document.
The following command packet format should be used for a Read Byte operation:
The following command packet format should be used for a Read Word operation:
The following command packet format should be used for a Read Block operation:
Write Transaction Protocol
Two main types of write transactions are used by this part: Write Byte and Write Word. The command packet format for a write transaction is dependent on the specific transaction type, which varies with respect to each PMBus command. The appropriate write transaction type for each command is specified in its designated section within this document.
