   In <i.MX Hardware Design Guide and Board Bring up> page31, it says Power on sequencing: VDD_SNVS_IN<=VDD_HIGH_IN<=any other power supply, but in <SPF-27516.pdf> page 19, MMPF0100F power on sequencing doesn't meet the requirement. VDD_HIGH_IN is the 11th. Does it matter? And if VDD_SNVS_IN is not the first power on, will the board not bring up?
