Notes 1. Even when the stop bit length is set to 2 bits by setting bit 2 (SL00) of asynchronous serial
interface mode register 00 (ASIM00), the stop bit detection in the case of reception is
performed with 1 bit.
2. Be sure to read reception buffer register 00 (RXB00) when an overrun error occurs. If not,
every time the data is received an overrun error is generated.
