Bit Bit Name
Initial
value R/W 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.
