If a communication error occurs while transmitting or receiving in UART mode, follow the procedures below:
•
(1) Set the RE bit in the U0C1 register to 0 (reception disabled).
(2) Set the RE bit in the U0C1 register to 1 (reception enabled).
•
(1) Set bits SMD2 to SMD0 in the U0MR register to 000b (serial interface disabled).
(2) Reset bits SMD2 to SMD0 in the U0MR register to 001b, 101b, and 110b.
(3) Write 1 to the TE bit in the U0C1 register (transmission enabled), regardless of the TE bit value in the
