When switching between smart card interface mode and standby mode, in order to retain the clock
duty, the following switching procedure should be used. Step (1) to step (7) of figure 30.10
correspond to the following operation.
• When switching from smart card interface mode to standby mode
1. Write 0 to the TE and RE bits in the serial control register (SCSCR), to stop transmit and
2. Write 0 to the CKE0 bit in SCSCR to stop the clock.
3. Wait for one cycle of the serial clock. During this interval, the duty is retained, and the clock
4. Make the transition to standby mode.
• To return from standby mode to smart card interface mode
5. Cancel the standby state.
6. Set the CKE1 bit in the serial control register (SCSCR) to the value of the output-fixed state at
7. Write 1 to the CKE0 bit in SCSCR to output a clock signal. Clock signal generation begins at

In order to retain the clock duty from power-on, the following switching procedure should be
used.
1. The initial state is set to port-input with high impedance. In order to fix the potential, a pull-up
2. Use the CKE1 bit in the serial control register (SCSCR) to fix the specified output.
3. Set the CKE0 bit in SCSCR to 1 to start clock output.
