Note 1: It’s prohiibited to control DFM in SLOW mode when shifting from SLOW mode to NORMAL mode with use of DFM.
Note 2: If you shift from NORMAL mode with use of DFM to NORMAL mode, the above two instructions should be separated
Note 3: It’s prohibited to shift from NORMAL mode with use of DFM to STOP mode directly. You should set NORMAL mode
The clock frequency input from the X1 and X2 pins is called fc, and the clock frequency input from the
XT1 and XT2 pins is called fs. The clock frequency selected by SYSCR1<SYSCK> is called the system
