13.3 Description of Operation
13.3.1
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 UART0 mode register (UA0MOD1).
Figure 13-2 and Figure 13-3 show the positive logicc input/output format and negative logic input/output format,
respectively.
