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 0 (ASIS0) is set as a result of data
reception, a reception error interrupt (INTSR0) is generated.
Which error has occurred during reception can be identified by reading the contents of ASIS0 in the reception
error interrupt (INTSR0) servicing (see Figure 13-3).
The contents of ASIS0 are cleared to 0 when ASIS0 is read.
The R
If two sampled values are the same, the output of the match detector changes, and the data is sampled as
input data.
Because the circuit is configured as shown in Figure 13-10, the internal processing of the reception operation
is delayed by two clocks from the external signal status.
Base clock
Reception Error
X
D0 signal is sampled using the base clock output by the prescaler block.
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 0 (RXB0).
