3.5.2 Mask options of POC circuit
The IE-789860-NS-EM1 includes a "POC switching circuit" that controls the power-on-clear circuit functions by
software. Perform the ON/OFF settings using an SFR.
When emulating the detection voltage of the low-voltage detection circuit and power-on-clear circuit, the detection
voltage must be finally checked with EEPROM
noise.
3.5.3 Mask options of oscillation stabilization wait time
The oscillation stabilization wait time of the IE-789860-NS-EM1 is fixed to 2
devices are shown in Table 3-6 below.
When emulating the oscillation stabilization wait time after the release of STOP mode by RESET or the release of
reset via the POC circuit, the oscillation stabilization wait time must be finally checked with EEPROM products
because of the effect of power supply fluctuations and noise.
