We/I power several modules with a 3.2V supply that we can turn OFF when we go into Standby/Sleep Mode.
When we turn the supply OFF, there is a lingering voltage of ~.8V that remains on this line.
We attach this 3.2V Supply onto the following modules……

Name Pad
NVCC_EIM_MAIN U9
NVCC_EIM_MAIN U10
NVCC_EIM_SEC U7
NVCC_SD1 H15
NVCC_SD2 H14
NVCC_DATA N7
NVCC_FEC F11
NVCC_GPIO F8
NVCC_KEYPAD F7
VDD_FUSE G15

My question is….
Could any of these be leaking voltage back onto this supply after we shut the 3.2V supply OFF? (From one of other module supplies or possibly a main core supply rail?)
