12.3 Description of Operation
12.3.1
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, 5 to 8 bits can
be selected as data bit. For the parity bit, “with parity bit”, “without parity bit”, “even parity”, or “odd parity” can be
selected. For the stop bit, “1 stop bit” or “2 stop bits” are available and for the transfer direction, “LSB first” or “MSB
first” are available for selection. For serial input/output logic, positive logic or negative logic can be selected.
All these options are set with the UARTn mode register
1 (UAnMOD1).
Figure 12-2 and Figure 12-3 show the positive logic input/output format and negative logic input/output format,
respectively.
