(2) Using free-running timer mode
(a) Interval operation using the TPnCCRa register as a compare register
When TMPn is used as an interval timer with the TPnCCRa register used as a compare register, the
comparison value at which the next interrupt request signal is generated each time the INTTPnCCa signal
has been detected must be set by software.
(CCR1 buffer register)
When performing an interval operation in the free-running timer mode, two intervals can be set for one
channel.
To perform the interval operation, the value of the corresponding TPnCCRa register must be set again in
the interrupt servicing that is executed when the INTTPnCCa signal is detected.
The value to be set in this case can be calculated by the following expression, where “D
period.
(CCR0 buffer 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 the register to
this value.)
