Section 13 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.
• Retransfer operation when SCI is in receive mode
[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.
[4] If no error is found when the received parity bit is checked, the receive operation is judged to
[5] When a normal frame is received, the pin retains the high-impedance state at the timing for

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
