Section 17 Subsystem Timer (Subtimer)
The division ratio of the on-chip oscillator to make the subclock be the setting cycle can be
obtained by the following formula.
In the subtimer, relationship between the setting values in ROPCR and the division ratio is as
follows.
Then the setting value m in ROPCR can be obtained by assigning the value k obtained by formula
(2) to formula (3).
The cycle to be actually used as the subclock is as follows.
Therefore, the rounding error between the expected value and the setting value of the subclock
cycle can be obtained by the following formula.
