2. The RDRF bit in SSR is not set for a frame in which an error has occurred.
3. If no error is found when the received parity bit is checked, the PER bit in SSR is not set to 1,
Figure 14.30 shows a flowchart for reception. A sequence of receive operations can be performed
automatically by specifying the DTC to be activated using an RXI interrupt source. In a receive
operation, an RXI interrupt request is generated when the RDRF flag in SSR is set to 1. If the RXI
request is designated beforehand as a DTC activation source, the DTC will be activated by the
RXI request, and the receive data will be transferred. The RDRF flag is cleared to 0 automatically
when data is transferred by the DTC. If an error occurs in receive mode and the ORER or PER
flag is set to 1, a transfer error interrupt (ERI) request will be generated. Hence, so the error flag
must be cleared to 0. In the event of an error, the DTC is not activated and receive data is skipped.
Therefore, receive data is transferred for only the specified number of bytes in the event of an
error. Even when a parity error occurs in receive mode and the PER flag is set to 1, the data that
has been received is transferred to RDR and can be read from there.
Note: For details on receive operations in block transfer mode, refer to section 14.4, Operation in

the receive operation is judged to have been completed normally, and the RDRF flag in SSR is
automatically set to 1. If the RIE bit in SCR is enabled at this time, an RXI interrupt request is
generated.
