(f) Reception error
Parity error
Framing error
Overrun error
Three types of errors may occur during reception: a parity error, framing error, or overrun error. If the error
flag of asynchronous serial interface reception error status register 6 (ASIS6) is set as a result of data
reception, a reception error interrupt request (INTSR6/INTSRE6) is generated.
Which error has occurred during reception can be identified by reading the contents of ASIS6 in the reception
error interrupt servicing (INTSR6/INTSRE6) (see Figure 11-6).
The contents of ASIS6 are reset to 0 when ASIS6 is read.
The error interrupt can be separated into reception completion interrupt (INTSR6) and error interrupt
(INTSRE6) by clearing bit 0 (ISRM6) of asynchronous serial interface operation mode register 6 (ASIM6) to
0.
1. If ISRM6 is cleared to 0 (reception completion interrupt (INTSR6) and error interrupt (INTSRE6) are
2. If ISRM6 is set to 1 (error interrupt is included in INTSR6)

Reception Error
The parity specified for transmission does not match the parity of the receive data.
Stop bit is not detected.
Reception of the next data is completed before data is read from receive buffer
register 6 (RXB6).
