Section 13 Serial Communication Interface
Bit 6—Character Length (CHR): Selects 7-bit or 8-bit data length in asynchronous mode. In
synchronous mode the data length is 8 bits regardless of the CHR setting.
Note: * When 7-bit data is selected, the MSB (bit 7) in TDR is not transmitted.
Bit 5—Parity Enable (PE): In asynchronous mode, this bit enables or disables the addition of a
parity bit to transmit data, and the checking of the parity bit in receive data. In synchronous mode
the parity bit is neither added nor checked, regardless of the PE setting.
Note: * When PE is set to 1, an even or odd parity bit is added to transmit data according to the
Bit 4—Parity Mode (O/E E E E ): Selects even or odd parity. The O/E bit setting is valid in
asynchronous mode when the PE bit is set to 1 to enable the adding and checking of a parity bit.
The O/E setting is ignored in synchronous mode, or when parity adding and checking is disabled
in asynchronous mode.
Notes: 1. When even parity is selected, the parity bit added to transmit data makes an even

checked to see that it matches the even or odd mode selected by the O/E bit.
