and the relationship of these pulses when the counter is in Count-Up/Down mode. In these figures,
the following definitions apply:
■ LOAD is the value in the PWMnLOAD register
■ COMPA is the value in the PWMnCMPA register
■ COMPB is the value in the PWMnCMPB register
■ 0 is the value zero
■ load is the internal signal that has a single-clock-cycle-width High pulse when the counter is
equal to the load value
■ zero is the internal signal that has a single-clock-cycle-width High pulse when the counter is zero
■ cmpA is the internal signal that has a single-clock-cycle-width High pulse when the counter is
equal to COMPA
■ cmpB is the internal signal that has a single-clock-cycle-width High pulse when the counter is
equal to COMPB
■ dir is the internal signal that indicates the count direction
