Notes:
U2LCH Bit (Data logic select bit)
After Reset
1. The RI bit is set to 0 (no data in the U2RB register) when the lower 8 bits in the U2RB register are read.
2. Set to 1 (transmission completed) when in I
3. Can only be set in SIO mode. In other modes, set to 0 (continuous receive mode disabled).
4. Can only be set in SIO/UART mode. In other modes, set to 0 (not inverted).
5. Set to 0 (output disabled).

Address 000C5h
Write to the U2C1 register using the MOV instruction.
This bit inverts the polarity of transmit data and receive data (data only). When the U2LCH bit is 1 (inverted),
the logic of data written to the U2TB register is inverted when writing data to the U2TB register during
transmission. When reading data from the U2TB register during reception, data with inverted logic is read.
