Serial Port Operation Description

12.4.1 Data Format

(1) UART mode
The data format for the UART mode is shown in Figure 12-3.
SRCON0/1 and STCON0/1 can be set to specify a data bit length of 5 to 8 bits. The parity bit can be
enabled/disabled. If enabled it can be set to even or odd. Stop bit length can be set to 1 or 2 bits.
The combination of these parameters gives a range of from 7 to 12 bits for send/receive data frames.

(2) Synchronous mode
The data format for the UART mode is shown in Figure 12-4.
SRCON0/1 and STCON0/1 can be set to specify a data bit length of 5 to 8 bits. The parity bit can be
enabled/disabled, and if enabled can be set to even or odd.
The combination of these parameters gives a range of from 5 to 9 bits for send/receive data frames.
