(3) Mode 2 (8-bit UART mode)
mode, a parity bit can be used. Parity can be enabled or disabled using SC0CR<PE>. When PE = 1
(parity enabled), even or odd parity can be selected using SC0CR<EVEN>.

Example: To transmit data in the following format, set the control registers as shown below.
Note: X = Don’t care; “—” = No change
