Section 14 Smart Card Interface
Retransfer Operations (Except Block Transfer Mode): Retransfer operations are performed by
the SCI in receive mode and transmit mode as described below.
[1] If an error is found when the received parity bit is checked, the PER bit in SSR is
[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.
[4] If no error is found when the received parity bit is checked, the receive operation is judged to

bit in SCR is enabled at this time, an RXI interrupt request is generated.
If DTC data transfer by an RXI source is enabled, the contents of RDR can be read
automatically. When the RDR data is read by the DTC, the RDRF flag is automatically cleared
to 0.
