We have used i.MX6ULL in our wearable medical product.
We want to connect unused power domain pins to ground which I/O pads are not used.
Ex. NVCC_UART pin supplies power to UART1-5 I/O pads.
If UART1-5 I/O pads are not used in an application then can we connect NVCC_UART pin to the ground?
Same can be done with other power domain pins which I/O pads are not used?
