PMIC
i.MX6 Qseven PMIC SOM supports Freescale’s MMPF0100 PMIC for On-SOM power management. The PMIC
provides all required power to i.MX6 CPU and all On SOM peripherals with programmable power management
solutions. This PMIC supports up to six buck converters, six linear regulators, RTC supply and coin-cell charger with
programmable output voltage, sequence and timing. i.MX6 CPU’s I2C2 interface is used for PMIC programmable. I2C
address for PMIC is 0x08.

Boot Switches
i.MX6 CPU boot process begins at Power On Reset (POR) where the hardware reset logic forces the ARM core to
begin execution starting from the on-chip boot ROM. i.MX6 CPU Boot ROM code uses the state of the internal
register BOOT_MODE [1:0] as well as the state of various eFUSEs and/or GPIO settings to determine the boot flow
behaviour of the device.
i.MX6 Qseven PMIC SOM supports two Boot switches for selecting Boot Mode setting and Boot Media setting of
i.MX6 CPU.
