(2) Mode 1 (7-bit UART Mode)
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" (enabled).
Setting example: When transmitting data of the following format, the control registers should be set as
described below.

(3) Mode 2 (8-Bit UART Mode)
8-Bit UART Mode is selected by setting SC0MOD0<SM1:0> to "10". 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
