NOTE:
NOTES:
1. Read-modify-write instructions cannot be used to set the UiTB register. Refer to Usage Notes for details.
1. Only a 0 can be written to the ABT bit.
2. When 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
3. Bits FER, PER and SUM are disabled when bits SMD2 to SMD0 in the UiMR register are set to 001b (clock synchronous mode)
0 (receive operation disabled), bits OER, FER, PER and SUM become 0.
When all of bits OER, FER and PER become 0, the SUM bit also becomes 0.
Bits FER and PER become 0 by reading the low-order byte in the UiRB register.
