(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:

(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:
