This procedure may include interrupt handling and DMA transfer.
If the RIE bit is set to 1 to enable interrupt requests, when receiving is completed and the RDRF
flag is set to 1, a receive-data-full interrupt (RXI) is requested. If a receive error occurs, either the
ORER or PER flag is set to 1 and a transmit/receive-error interrupt (ERI) is requested.
If the RXI interrupt activates the DMAC, the number of bytes designated in the DMAC will be
transferred, skipping receive data in which an error occurred.
For details, see Interrupt Operations and Data Transfer by DMAC below.
When a parity error occurs and PER is set to 1, the receive data is transferred to RDR, so the
erroneous data can be read.
Switching Modes
To switch from receive mode to transmit mode, check that receiving operations have completed,
then initialize the smart card interface, clearing RE to 0 and setting TE to 1. Completion of receive
operations is indicated by the RDRF, PER, or ORER flag.
To switch from transmit mode to receive mode, check that transmitting operations have
completed, then initialize the smart card interface, clearing TE to 0 and setting RE to 1.
Completion of transmit operations can be verified from the TEND flag.
Fixing Clock Output
When the GM bit of the SMR is set to 1, clock output is fixed by CKE1 and CKE0 of SCR. In this
case, the clock pulse can be set at minimum value.
Figure 14.8 shows clock output fixed timing: CKE0 is restricted with GM = 1 and CKE1 = 1.
