Address 00A7h to 00A6h (U0RB)
- Bits SMD2 to SMD0 in the U0MR register are set to 000b (serial interface disabled), or
- The RE bit in the U0C1 register is set to 0 (reception disabled)
The SUM bit is set to 0 (no error) when all of bits PER, FER, and OER are set to 0 (no error).
Bits PER and FER are also set to 0 when the high-order byte of the U0RB register is read.
Always read the U0RB register in 16-bit units.
