Warning (11106): Shared VREF is used as GPIO <pin name>. This action reduces fmax performance.
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description VREF pins have a high pin capacitance than other pins in devices that support dual-purpose VREF pins. Avoid using the VREF pins as an I/O pin of a bus or clock function because the higher capacitance will slow the edge rates and affect I/O timing.
