(2) Asynchronous serial interface status registers 0, 1 (ASIS00, ASIS01)
ASIS00 and ASIS01 are the registers that indicate the error contents when a receive error occurs.
These registers can be read with an 8-bit memory manipulation instruction.
RESET input clears these registers to 00H.
Notes 1. Even if the stop bit length is set to 2 bits using bit 2 (SL00) of asynchronous serial interface mode

2. If an overrun error occurs, be sure to read receive buffer register 0 (RXB00). Until RXB00 is read,
