Slave address (7bit) = 42[hex] or 43[hex] in respect of MAD.
Read/Write bit: 0 = write to component; 1 = master reads from component.
byte which indicates register of component which the are data for.

If more than one byte of data is transmitted, then auto-increment of subaddress is performed.
i.e. transmit 3 bytes starting with data for switch register
