(b) Asynchronous serial interface status registers 0, 1 (ASIS00, ASIS01)
Notes 1. Even if the stop bit length is set to 2 bits using bit 2 (SL0n) of asynchronous serial interface mode
Remark n = 0, 1
ASIS00 and ASIS01 can be read with an 8-bit memory manipulation instruction.
RESET input clears these registers to 00H.

2. If an overrun error occurs, be sure to read receive buffer register n (RXB0n). Until RXB0n is read,
register n (ASIM0n), only 1 stop bit is detected during reception.
an overrun error persistently occurs each time data is received.

Parity error does not occur.
Parity error occurs (transmit data parity
specification and receive data parity do not
match).
Framing error does not occur.
Framing error occurs
(stop bit not detected).
Overrun error does not occur.
Overrun error occurs
completed before data is read from receive
