Description

CHR

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.

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.

R/W

Parity mode

Selects even or odd parity when parity bits are added and

checked. The O/

E setting is used only in asynchronous

mode and only when the parity enable bit (PE) is set to 1 to

enable parity addition and checking. The O/

E setting is

ignored in synchronous mode, or in asynchronous mode

when parity addition and checking is disabled.

0: Even parity*

1: Odd parity*

Notes:1. If even parity is selected, the parity bit is added

to transmit data to make an even number of 1s in

the transmitted character and parity bit

combined. Receive data is checked to see if it

has an even number of 1s in the received

character and parity bit combined.

2. If odd parity is selected, the parity bit is added to

transmit data to make an odd number of 1s in the

transmitted character and parity bit combined.

Receive data is checked to see if it has an odd

number of 1s in the received character and parity

bit combined.
