21.3.1
If communication is aborted or a communication error occurs while transmitting or receiving in clock
synchronous serial I/O mode, follow the procedures below:
(1) Set the TE bit in the U0C1 register to 0 (transmission disabled) and the RE bit to 0 (reception disabled).
(2) Set bits SMD2 to SMD0 in the U0MR register to 000b (serial interface disabled).
(3) Set bits SMD2 to SMD0 in the U0MR register to 001b (clock synchronous serial I/O mode).
(4) Set the TE bit in the U0C1 register to 1 (transmission enabled) and the RE bit to 1 (reception enabled).
