(1) Set the TE bit in the UiC1 register (i = 0 or 1) to 0 (transmission disabled) and the RE bit to 0 (reception
(2) Set bits SMD2 to SMD0 in the UiMR register to 000b (serial interface disabled).
(3) Set bits SMD2 to SMD0 in the UiMR register to 001b (clock synchronous serial I/O mode).
(4) Set the TE bit in the UiC1 register to 1 (transmission enabled) and the RE bit to 1 (reception enabled).
If communication is aborted or a communication error occurs while transmitting or receiving in clock
synchronous serial I/O mode, follow the procedures below:
