I want to ask you about i.MX6ULL.
I want to know the state of the pins during POR is asserted.
Does it have been described in the manual or data sheet?
refer to the data sheet:
"The SRC_POR_B signal controls the processor POR and must be immediately asserted atpower-up and remain asserted until the VDD_ARM_CAP, VDD_SOC_CAP, and VDD_PU_CAPsupplies are stable. VDD_ARM_IN and VDD_SOC_IN may be applied in either order with norestrictions."
for more detailed information, pls refer to the Power-Up Sequence of data sheet.
There are pin states, provided in the DataSheet(s), relate to situation just after reset ;
pin states during power on \ reset are not guaranteed.
