13. Smart Card Interface
If reception ends and the RDRF flag is set to 1 while the RIE bit is set to 1 and interrupt requests
are enabled, a receive-data-full interrupt (RXI) will be requested. If an error occurs in reception
and either the ORER flag or the PER flag is set to 1, a transmit/receive-error interrupt (ERI) will
be requested.
For details, see Interrupt Operations in this section.
If a parity error occurs during reception and the PER flag is set to 1, the received data is
transferred to RDR, so the erroneous data can be read.
Switching Modes: When switching from receive mode to transmit mode, first confirm that the
receive operation has been completed, then start from initialization, clearing RE to 0 and setting
TE to 1. The RDRF, PER, or ORER flag can be used to check that the receive operation has been
completed.
When switching from transmit mode to receive mode, first confirm that the transmit operation has
been completed, then start from initialization, clearing TE to 0 and setting RE to 1. The TEND
flag can be used to check that the transmit operation has been completed.
Fixing Clock Output: When the GM bit is set to 1 in SMR, clock output can be fixed by means
of the CKE1 and CKE0 bits in SCR. The minimum clock pulse width can be set to the specified
width in this case.
Figure 13.9 shows the timing for fixing clock output. In this example, GM = 1, CKE1 = 0, and the
CKE0 bit is controlled.
