E.2
When the STBY pin level changes from low to high after powering on, the chip goes to the power-
on reset state after a high level is detected at the STBY pin. While the chip detects a low level at
the STBY pin, it is in the hardware standby mode. During this interval, the pins are in the high-
impedance state.
After detecting a high level at the STBY pin, the chip starts oscillation.
