Section 13 Smart Card Interface
Serial Data Reception: Data reception in Smart Card mode uses the same processing procedure
as for the normal SCI. Figure 13.7 shows an example of the transmission processing flow.
[1] Perform Smart Card interface mode initialization as described above in Initialization.
[2] Check that the ORER flag and PER flag in SSR are cleared to 0. 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] When receiving data continuously, clear the RDRF flag to 0 and go back to step [2].
[6] To end reception, clear the RE bit to 0.
