(4) Power-On and Clock

The following procedure should be used 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

potential.

2. Fix at the output specified by the CKE1 bit in the serial control register (SCSCR1).

3. Set the serial mode register (SCSMR1) and smart card mode register (SCSCMR1), and switch

to smart card mode operation.

4. Set the CKE0 bit in SCSCR1 to 1 to start clock output.
