Data Transfer Format
Send byte format—the send byte protocol is used to set up the register address for subsequent commands.
S
Write byte format—the write byte protocol is used to write a register address to the RAM starting from the specified RAM address.
S
Receive byte format—the receive byte protocol is used to read the data byte(s) from RAM starting from the current address.
S
Read byte format—the combined format of the send byte and the receive byte.
