Select a frequency division ratio that stays within the assured operation range specified for the
clock cycle time t
limit of the clock frequency range. Avoid settings that give system clock frequencies less than
the lower limit.
Table 19.6 shows the comparison with the clock frequency range for each version.
All on-chip module operations are based on . Note that the timing of timer operations, serial
communication, and other time-dependent processing differs before and after any change in
the division ratio. The waiting time for exit from software standby mode also changes when
the division ratio is changed. For details, see section 20.4.3, Selection of Waiting Time for Exit
from Software Standby Mode.
