Continuous receive mode is selected by setting the U0RRM bit in the U0C1 register to 1 (continuous receive
mode enabled). In this mode, reading the U0RB register sets the TI bit in the U0C1 register to 0 (data present in
the U0TB register). When the U0RRM bit is 1, do not write dummy data to the U0TB register by a program.
If communication is aborted or a communication error occurs while transmitting or receiving in clock
synchronous serial I/O mode, follow the procedure 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).
