Main oscillator (R-OSCI, OSCO), such as RC oscillator with external resistor and Internal capacitor mode (ERIC); b.) Crystal oscillator mode; and c.) PLL operation mode (R-OSCI connected to 0.01μF capacitor to Ground). User can select which mode by programming FMMD1 and FMMD0 in the Code Options Register.

EM78P468N/EM78P468L 8-Bit Microcontroller 6.7.1 External Power-on Reset Circuit This circuit implements an external RC to produce a reset pulse (see Fig. 6-10). The pulse width (time constant) should be kept long enough to allow VDD to reach minimum operation voltage. This circuit is used when the power supply rise time is slow. Because the current leakage from the /RESET pin is ±5μA, it is recommended that R should not be greater than 40K. In this way, the voltage at Pin /RESET is held below 0.2V.

Fig. 6-22 LGP=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.
