Description

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 clocked 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 clocked 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.
