list pin settings. Figure 22.29 shows an example of transmit and receive operation.
When the OPOL bit in the GiCR register is set to "0" (ISTxD output polarity not inversed), the ISTxDi pin
puts in a high-level ("H") signal output after selecting operating mode until transfer starts. When the OPOL
bit is set to "1" (ISTxD output polarity inversed), the ISTxDi pin puts in a low-level ("L") signal output.
