(2) Mode 1 (7-bit UART M ode)
7-Bit UART Mode is selected by setting the Serial Channel Mode Register
SC0MOD0<SM1:0> field to 01.
In this mode a parity bit can be added. Use of a parity bit is enabled or disabled by the
setting of the Serial Channel Control Register SC0CR<PE> bit; whether even parity
or odd parity will be used is determined by the SC0CR<EVEN> setting when
SC0CR<PE> is set to 1 ( e nabled).
Setting example: When transmitting data of the following format, the control
registers should be set as described below.

(3) Mode 2 (8-Bi t UART Mode)
8-Bit UART Mode is selected by settin g SC0MOD0<SM1,SM0> to 1 0. In this mode a
parity bit can be added (use of a parity bit is enabled or disabled by the setting of
SC0CR<PE>); whether even parity or odd parity will be used is determined by the
SC0CR<EVEN> setting when SC0CR<PE> is set to 1 (enabled).
Setting example: When receiving data of the following format, the control
registers should be set as described below.
