When Changing from Smart Card Interface Mode to Software Standby Mode:
1. Set the data register (DR) and data direction register (DDR) corresponding to the SCK pin to
2. Write 0 to the TE bit and RE bit in the serial control register (SCR) to halt transmit/receive
3. Write 0 to the CKE0 bit in SCR to halt the clock.
4. Wait for one serial clock cycle.
5. Make the transition to the software standby state.
When Returning to Smart Card Interface Mode from Software Standby Mode:
1. Exit the software standby state.
2. Write 1 to the CKE0 bit in SCR and output the clock. Signal generation is started with the
