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?
There are pin states, provided in the DataSheet(s), relate to situation just after reset ;
pin states during power on \ reset are not guaranteed.
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.
