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 TQ0CCRm register must be re-set in the
interrupt servicing that is executed when the INTTQ0CCm signal is detected.
The set value for re-setting the TQ0CCRm register can be calculated by the following expression, where “D
m” is
the interval period.
Compare register default value: D
m − 1
Value set to compare register second and subsequent time: Previous set value + D
m
(If the calculation result is greater than FFFFH, subtract 10000H from the result and set this value to the
register.)
Remark m = 0 to 3
