If communication is aborted or a communication error occurs while transmitting or receiving in UART mode,
follow the procedures below:
(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 100b (UART mode, transfer data 7 bits long), 101b
(4) Set the TE bit in the UiC1 register to 1 (transmission enabled) and the RE bit to 1 (reception enabled).
disabled).
(UART mode, transfer data 8 bits long), or 110b (UART mode, transfer data 9 bits long).
