The setting of the PWM channel used for combining can be selected as follows:

Regarding the PWM_SEL_DISm, when bit0 is “0”, the corresponding PWM becomes valid, when “1”, the
corresponding PWM becomes invalid.
Regarding bit 1 to bit 7, when they are “1”, the corresponding PWM becomes valid, when “0”, the corresponding
PWM becomes invalid. In either case, the PWM channels that were made invalid are treated as “1” output.
Regarding the PWM_SEL_INVm, the PWM channels corresponding to each bit are inverted by “1”.
When performing OR combining by the PWM_SELm field setting, disable the channels that are not used by
PWM_SEL_DISm and then also make an invert setting for PWM_SEL_INVm (input “0” at the OR combining
stage).
Note that at the reset initial state, these registers are All 0 and the output terminal PWMm (m = 0, ..., 3) is in a
state that the internal PWMm can be output without being combined and inverted.
3.9.11.7
PWM_TIMER
Channels that are not used as the PWM function can be used as general-purpose timers. The settings are the
same as PWM.
Also, interrupts can be generated at the timing of each falling edge of the PWM output (PWM cycle).
Note that for the internal sequencer, a total of three signals are generated by ORing arbitrarily selected eight
channels and provided as interrupt signals.
For the upper CPU, each of eight channels of PMW timer interrupt is output via the INT_SEL module. Please also
refer to Section 3.9.6.2.
