transmission.

0000: Reads slave status

0001: Undefined*

0010: Undefined*

0011: Reads data and locks*

0100: Reads locked address (lower 8 bits)

0101: Reads locked address (upper 4 bits)

Notes: 1. CTL3 decides the data transfer direction of the message length bits in the message

length field and data bits in the data field:

CTL3 = 1: Transfer is from master unit to slave unit

CTL3 = 0: Transfer is from slave unit to master unit
