The PRUSS UART0 transmits in the following format:
| 1 START bit + data bits (5, 6, 7, 8) + 1 PARITY bit (optional) + STOP bit (1, 1.5, 2) |
It transmits 1 START bit; 5, 6, 7, or 8 data bits, depending on the data width selection; 1 PARITY bit, if parity is selected; and 1, 1.5, or 2 STOP bits, depending on the STOP bit selection.
The PRUSS UART0 receives in the following format:
| 1 START bit + data bits (5, 6, 7, 8) + 1 PARITY bit (optional) + 1 STOP bit |
It receives 1 START bit; 5, 6, 7, or 8 data bits, depending on the data width selection; 1 PARITY bit, if parity is selected; and 1 STOP bit.
The protocol formats are shown in Figure 7-44.
