Page 27: System Resets
SOM-IMX8MM Hardware User Manual 10. System Resets 10.1 Power-on Reset This type of reset occurs when the power is initially applied to the SOM-IMX8M-MINI. As the supply voltage rises, the on-board PMIC holds the i.MX 8M MINI in reset until all the processor power supply voltages have risen above the appropriate voltage thresholds (90% of the nominal values). -
