Section 15 Smart Card Interface
1. Initialize the smart card interface mode as described above in Initialization and in figure 15.5.
2. Check that the ORER and PER flags in SCSSR are cleared to 0. If either flag is set, clear both
3. Repeat steps 2 and 3 until the RDRF flag is set to 1.
4. Read the receive data from SCRDR.
5. To receive more data, clear the RDRF flag to 0 and return to step 2.
6. To end reception, clear the RE bit to 0.
This processing can be interrupted. When the RIE bit is set to 1 and interrupt requests are enabled,
a receive-data-full interrupt (RXI) will be requested when the RDRF flag is set to 1 at the end of
the reception. When an error occurs during reception and either the ORER or PER flag is set to 1,
a communication error interrupt (ERI) will be requested. See Interrupt Operation below for more
information.
The received data will be transferred to SCRDR even when a parity error occurs during reception
and PER is set to 1, so this data can still be read.
