Note Set the serial clock to satisfy the following conditions.
Cautions 1. When the internal oscillation clock is selected as the clock supplied to the CPU, the clock of

2. Do not write to CSIC11 while CSIE11 = 1 (operation enabled).
3. Clear CKP11 to 0 to use P02/SO11, P03/SI11, and P04/SCK11 as general-purpose port pins.
4. The phase type of the data clock is type 1 after reset.
