EM78P341N/342N/343N
8-Bit Microprocessor with OTP ROM
6.8.2 Function Description
The following figure shows LGP=0 and HF=1. The IROUT waveform modulates the
Fcarrier waveform at low-time segments of the pulse.

The following figure shows LGP=0 and HF=0. The IROUT waveform cannot modulate
the Fcarrier waveform at low-time segments of the pulse. So IROUT waveform is
determined by the high time width and low time width instead. This mode can produce
standard PWM waveform.
