generated, and the RIE bit should be set to 1 so that an ERI request is issued. The ERS flag set
when an error signal is received is not cleared automatically, and so should be cleared by sending
an interrupt request to the CPU.
In receive operation, when the RDRF flag in SCSSR is set to 1, a DMA transfer request for
receive data full is issued. By setting a DMA transfer request for receive data full in advance as a
DMAC activation source, the DMAC can be activated and made to transfer data when a DMA
transfer request for receive data full occurs.
When in T = 0 mode and if a parity error occurs during reception, a data retransmit request is
issued. At this time the RDRF flag is not set, and a DMA transfer request is not issued, so the
number of bytes specified to the DMAC can be received.
When using the DMAC for receive data processing and performing error processing as a result of
an interrupt request sent to the CPU, the RIE bit should be set to 1 and the EIO bit to 1, so that no
RXI requests are generated and only ERI requests are generated.
The PER, ORER, and WAIT_ER flags that are set by a receive error are not automatically cleared,
and so should be cleared by sending an interrupt request to the CPU.
When using the DMAC for transmission and reception, the DMAC should always be set first and
put into the enabled state, before setting the smart card interface.
