1 SCINV5 0 R/W TXD33 Pin Output Data Inversion Switch
Specifies whether the logic level of output data of the
TXD33 pin is inverted.
0: TXD33 output data is not inverted
1: TXD33 output data is inverted
0 SCINV4 0 R/W RXD33 Pin Input Data Inversion Switch
Specifies whether the logic level of input data of the
RXD33 pin is inverted.
0: RXD33 input data is not inverted
1: RXD33 input data is inverted
Note: When the serial port control register 2 is modified, the data being input or output up to that
point is inverted immediately after the modification, and an invalid data change is input or
output. When modifying the serial port control register 2, modification must be made in a
state in which data changes are invalidated.
