Receiving Serial Data: The receiving procedure in smart card mode is the same as the normal
SCI procedure. Figure 14.7 shows a flowchart for receiving.
1. Initialize the smart card interface by the procedure given in Initialization at the beginning of
2. Check that the ORER and PER error flags are cleared to 0 in SSR. If either flag is set, carry out
3. Check that the RDRF flag is set to 1. Repeat steps 2 and 3 until this check passes.
4. Read receive data from RDR.
5. To continue receiving data, clear the RDRF flag to 0 and return to step 2.
6. To terminate receiving, clear the RE bit to 0.
