Description

6 CHR 0 R/W

Character

Length

Selects 7-bit or 8-bit data in asynchronous mode. In the
synchronous mode, the data length is always eight bits,
regardless of the CHR setting.

0: 8-bit data

1: 7-bit data*

Note: * When 7-bit data is selected, the MSB (bit 7) of

the transmit FIFO data register is not
transmitted.

5 PE 0 R/W

Parity

Enable

Selects whether to add a parity bit to transmit data and
to check the parity of receive data, in asynchronous
mode. In synchronous mode, a parity bit is neither
added nor checked, regardless of the PE setting.

0: Parity bit not added or checked

1: Parity bit added and checked*

Note: * When PE is set to 1, an even or odd parity bit

is added to transmit data, depending on the
parity mode (O/

E) setting. Receive data parity

is checked according to the even/odd (O/

E)

mode setting.
