14. Smart Card Interface
From the above equation, if F = 0 and D = 0.5, the receive margin is as follows.
When D = 0.5 and F = 0:
Retransmission: Retransmission is performed by the SCI in receive mode and transmit mode as
described below.
• Retransmission when SCI is in Receive Mode
1. If an error is found when the received parity bit is checked, the PER bit is automatically set to
2. The RDRF bit in SSR is not set for the frame in which the error has occurred.
3. If no error is found when the received parity bit is checked, the PER bit is not set to 1 in SSR.
4. If no error is found when the received parity bit is checked, the receive operation is assumed to
5. When a normal frame is received, the data pin is held in the high-impedance state at the error

have been completed normally, and the RDRF bit is automatically set to 1 in SSR. If the RIE
bit in SCR is set to the enable state, an RXI interrupt is requested. If RXI is enabled as a DMA
transfer activation source, the RDR contents can be read automatically. When the DMAC
reads the RDR data, the RDRF flag is automatically cleared to 0.
