11.3.2 Asynchronous Serial Interface (UART)
11.3.2.1 Transfer Data Format
In the transfer data format, one frame contains a start bit, a data bit, a parity bit, and a stop bit. In this format, the
following are chooseable: 5 to 8 bits for the data bit, availability of parity, even/odd parity, parity fixed to "1", or parity
fixed to "0" for the parity bit, 1 stop bit or 2 stop bit for the stop bit, LSB first or MSB first for the transfer direction, and
positive logic or negative logic for the logic of the serial input/output.
All of these are set in the UARTn mode register (UAnMOD).
Figure 11-12 and Figure 11-13 show the positive logic input/output format and negative logic input/output format,
respectively.
