The following points should be noted in clock division mode.
• Select the clock division ratio by the STC1 and STC0 bits so that the frequency of φ is within
• All the on-chip peripheral modules operate on the φ. Therefore, note that the time processing
• Note that the frequency of φ will be changed by changing the clock division ratio.

the operation guaranteed range of clock cycle time tcyc shown in the Electrical Characteristics.
In other words, the frequency of φ must be 8 MHz or higher; be careful not so specify φ < 8
MHz.
of modules such as a timer and SCI differ before and after changing the clock division ratio. In
addition, the wait time for clearing software standby mode differs by changing the clock
division ratio.
