(2) Operation timing in free-running timer mode
(a) Interval operation with TAAnCCRm register used as compare register
When 16-bit timer/event counter AA is used as an interval timer with the TAAnCCRm register used as a
compare register, software processing is necessary for setting a comparison value to generate the next
interrupt request signal each time the INTTAAnCCm signal has been detected.
When performing an interval operation in the free-running timer mode, two intervals can be set with one
channel.
To perform the interval operation, the value of the corresponding TAAnCCRm register must be re-set in the
interrupt servicing that is executed when the INTTAAnCCm signal is detected.
The set value for re-setting the TAAnCCRm register can be calculated by the following expression, where
“D

register.)
