3. TECHNICAL BRIEF
- 38 -
Input ON is a power-on input for SM-POWER with 2 active high levels (see Figure 8). It might be
triggered by a push button or by the RTCOUT output of the S-GOLD device as well. To detect if the
push-button is pressed during system operation the logical level at pin ON or its change (if Bit 1 EION
in INTCTRL2 is asserted) is recorded in bit LON of the ISF register. If the high level of voltage at pin
ON does not reach VIHdet (Vbat-0.8 ~ Vbat-0.3) the above-mentioned bit won’t be set.
To support Remote power on function for factory mass production, applied an analog switch as
following figure. As monitoring the RPWRON(GPIO_109) and Key matrix KP_OUT(1) & KP_IN(5),
KE850 system recognize whether remote power on or End-key pushed
