When turning on the power or switching between Smart Card interface mode and software
standby mode, the following procedures should be followed in order to maintain the clock duty.
Powering on: To secure clock duty from power-on, the following switching procedure should be
followed.
1. The initial state is port input and high impedance. Use a pull-up resistor or pull-down resistor
2. Fix the SCK pin to the specified output level with the CKE1 bit in SCR.
3. Set SMR and SCMR, and switch to smart card mode operation.
4. Set the CKE0 bit in SCR to 1 to start clock output.
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 period.
5. Make the transition to the software standby state.
to fix the potential.
the value for the fixed output state in software standby mode.
operation. At the same time, set the CKE1 bit to the value for the fixed output state in software
standby mode.
During this interval, clock output is fixed at the specified level, with the duty preserved.
