Receiving Serial Data: Data reception in smart card mode uses the same processing procedure as
for the normal SCI. Figure 13.8 shows a sample reception processing flowchart.
1. Perform smart card interface mode initialization as described in Initialization above.
2. Check that the ORER flag and PER flag are cleared to 0 in SSR. If either is set, perform the
3. Repeat steps 2 and 3 until it can be confirmed that the RDRF flag is set to 1.
4. Read the receive data from RDR.
5. To continue receiving data, clear the RDRF flag to 0 and go back to step 2.
1. Data write
2. Transfer from TDR to TSR
3. Serial data output
