Hello,community
About i.MX 7Dual Applications Processor Reference Manual, Table 6-8. Power mode transitions (Configuration with internal PMIC, Power mode (ON, first time))
If the voltage is applied only to VDD_SNVS_IN among the power supply terminals and POR_B is low, when the button is pressed, will 'state' be ON and PMIC_ON_REQ will be '1'?

Hi,
From diagram, we know logical relations:
FSM module will check time that button is pressed and kept, check if time <5s or >5s, determine power on or Power off.
Power On, PMIC_ON_REQ is HIGH or high Z, see above diagram. Power Off , PMIC_ON_REQ =0.
Have a nice day!

Hi,
About Table 6-8 and Figure 6-4 in i.MX 7 Dual Applications Processor Reference Manual
After the first VSNVS, until the ONOFF pin button in Figure 6-4 is pressed, is PMIC_ON_REQ still "0(Low)"?
Or is "1(high)" output for PMIC_ON_REQ regardless of the ONOFF pin button?
Is PMIC_ON_REQ output even if POR_B is "0(Low)" at this time?
