12.2.5
The serial mode register (SMR) is an 8-bit register that specifies the SCI serial communication
format and selects the clock source for the baud rate generator.
The CPU can always read and write the SMR. The SMR is initialized to H'00 by a power-on reset.

Bit 5: PE

Bit 7—Reserved. This bit always reads 0. The write value should always be 0.
Bit 6—Character Length (CHR): Selects 7-bit or 8-bit data in the asynchronous mode.
Bit 5—Parity Enable (PE): Selects whether to add a parity bit to transmit data and to check the
parity of receive data.

Description
Eight-bit data (initial value)
Seven-bit data. (When 7-bit data is selected, the MSB (bit 7) of the
transmit data register is not transmitted.)
Description
Parity bit not added or checked (initial value)
Parity bit added and checked. 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.
