NOTES:
1.
2. Set the UiRRM bit to 0 (disables continuous receive mode) in UART mode.
1.
2.
The RI bit is set to 0 w hen the higher byte of the UiRB register is read out.
Read out the UiRB register in 16-bit units.
Bits SUM, PER, FER, and OER are set to 0 (no error) w hen bits SMD2 to SMD0 in the UiMR register are set to 000b
(serial interface disabled) or the RE bit in the UiC1 register is set to 0 (receive disabled). The SUM bit is set to 0 (no
error) w hen bits PER, FER, and OER are set to 0 (no error). Bits PER and FER are set to 0 even w hen the higher byte
of the UiRB register is read out.
Also, bits PER and FER are set to 0 w hen reading the high-order byte of the UiRB register.
