14. Smart Card Interface
2. Write 0 in the TE and RE bits in the serial control register (SCR) to stop transmit/receive
3. Write 0 in the CKE0 bit in SCR to stop the clock.
4. Wait for one serial clock cycle. During this period, the duty cycle is preserved and clock output
5. Write H'00 in the serial mode register (SMR) and smart card mode register (SCMR).
6. Make the transition to the software standby state.
• Returning from software standby mode to smart card interface mode
1′. Clear the software standby state.
2′. Set the CKE1 bit in SCR to the value for the fixed output state at the start of software standby
3′. Set smart card interface mode and output the clock. Clock signal generation is started with the
Use the following procedure to secure the clock duty cycle after powering on.
1. The initial state is port input and high impedance. Use pull-up or pull-down resistors to fix the
2. Fix at the output specified by the CKE1 bit in SCR.
3. Set SMR and SCMR, and switch to smart card interface mode operation.
4. Set the CKE0 bit to 1 in SCR to start clock output.
