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.
Note: * Excerpt for the H8S/2357 ZTAT, all resets are power-on resets, regardless of the level on the NMI pin.
