Examples of Operation in GSM Mode: When switching between smart card interface mode and
software standby mode, use the following procedures to maintain the clock duty cycle.
1. Set the P9
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.
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
