(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 6n (ASIS6n) is set as a result of data
reception, a reception error interrupt request (INTSR6n/INTSRE6n) is generated.
Which error has occurred during reception can be identified by reading the contents of ASIS6n in the
reception error interrupt servicing (INTSR6n/INTSRE6n) (see Figure 14-9, 14-10).
The contents of ASIS6n are cleared to 0 when ASIS6n is read.
The error interrupt can be separated into reception completion interrupt (INTSR6n) and error interrupt
(INTSRE6n) by clearing bit 0 (ISRM6n) of asynchronous serial interface operation mode register 6n
(ASIM6n) to 0.
1. If ISRM6n is cleared to 0 (reception completion interrupt (INTSR6n) and error interrupt (INTSRE6n)
2. If ISRM6n is set to 1 (error interrupt is included in INTSR6n)

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 6n (RXB6n).
