(2) Operation timing in free-running timer mode
(a) Interval operation with compare register
When 16-bit timer/event counter AA is used as an interval timer with the TAAnCCRa 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 INTTAnCCa 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 TAAnCCRa register must be re-set in the
interrupt servicing that is executed when the INTTAnCCa signal is detected.
The set value for re-setting the TAAnCCRa register can be calculated by the following expression, where
“D
Remark
TAAnCCR1 register
TAAnCCR0 register
Compare register default value: D
Value set to compare register second and subsequent time: Previous set value + D
(If the calculation result is greater than FFFFH, subtract 10000H from the result and set this value to the
register.)
