For the mk64fn1m0Vdc12 device, can you confirm if the VREFH is tied to VDDA in the 121 XBGA package? The datasheet ball out lists VREFH as a pin, so it implies it is not shorted to VDDA. Can you confirm?


Can I generally say if VDDA and VREFH are pinned out they are not connected internally. If I recall they are connected internally only on lower pin count parts.
