The IROUT output waveform is further explained in the following figures:

Fig. 6-21LGP=0, HF=1, the IROUT waveform can modulate Fcarrier waveform when in low-pulse width time.

Fig. 6-22LGP=0, HF=0, the IROUT waveform cannot modulate Fcarrier waveform when in low-pulse width time. So IROUT waveform is determined by high-pulse time and low-pulse time. This mode can produce standard PWM waveform.

Fig. 6-23LGP=0, HF=1, the IROUT waveform can modulate Fcarrier waveform when in low-pulse width time. When IRE goes from high to low, the output waveform of IROUT will keep on transmitting until high-pulse width timer interrupt occurs.

Fig. 6-24LGP=0, HF=0, the IROUT waveform can not modulate Fcarrier waveform when in low-pulse width time. So IROUT waveform is determined by high-pulse time and low-pulse time. This mode can produce standard PWM waveform. When IRE goes from high to low, the output waveform of IROUT will keep on transmitting till high-pulse width timer interrupt occurs.

Fig.6-25LGP=1, when this bit is set to high level, the high-pulse width timer is ignored. So IROUT waveform output from low-pulse width timer is established.
