Data Format

There are several data formats, which can be applied for serial I/O, these are summarized here:

Data length

7 – 8 – 9 bits (9-bit data is practicable for a multi controller system)

Stop bit

1 – 2 bits

Parity bit

provided/not provided

Parity system

even/odd

Start bit

1-bit fixed

data format

MSB/LSB first (switchable by register settings)

Please note that sending a parity bit is not allowed for address transmission in a multi-controller

system, Figure 10.1.2 and Figure 10.1.3 show examples for these data formats:
