The SCI can carry out serial communication in two modes: asynchronous mode in which
synchronization is achieved character by character, and synchronous mode in which
synchronization is achieved with clock pulses. A smart card interface is also supported as a serial
communication function for an IC card interface.
Selection of asynchronous or synchronous mode and the transmission format for the normal serial
communication interface is made in SMR, as shown in table 12.8. The SCI clock source is
selected by the C/
For details of the procedures for switching between LSB-first and MSB-first mode and inverting
the data logic level, see section 13.2.1, Smart Card Mode Register (SCMR).
For selection of the smart card interface format, see section 13.3.3, Data Format.
