Read back Descriptions
Single parameter read back:
Functions can be read back one
at a time using the read_word_protocol with PEC. A
command is first sent out notifying the slave what function is
to be read back followed by the data transfer.
Analog data is always transmitted LSB followed by MSB. A NA
following the PEC byte signifies that the transmission is
complete and is being terminated by the ‘host’.
