Mode 1 (7-bit UART Mode)
The 7-bit mode can be set by setting serial channel
mode register SC0MOD <SM1, 0> /SC1MOD <SM1,
0> to “01”.
In this mode, a parity bit can be added, and the addition of a parity bit can be enabled or disabled by serial
channel control register SC0CR <PE> /SC1CR <PE>,
and even parity or odd parity is selected by SC0CR
<EVEN> /SC1CR <EVEN> when <PE> is set to “1”
(enable).
Setting example:
When transmitting data with the
following format, the control
registers should be set as described
below. Channel 0 is explained here.

Mode 2 (8-bit UART Mode)
The 8-bit UART mode can be specified by setting
SC0MOD <SM1, 0> / SC1MOD <SM1, 0> to “10”. In
this mode, parity bit can be added, the addition of a
parity bit is enabled or disabled by SC0CR <PE> /
SC1CR <PE>, and even parity or odd parity is selected
by SC0CR <EVEN>/SC1CR <EVEN> when <PE> is
set to “1” (enable).
Setting example:
When receiving data with the
following format, the control register
should be set as described below.
