I'm looking for some advice with my emulator question. I'm emulating the GZ60 with the MMDS/EML08GZ combination. Everything works OK, but I want toCHANGE VREFH.
The emulation daughter card simply connects VRFH to VDDA via a 38R ferrite bead. I have my own reference voltage on the target, and wonder how to configure the EML board to accept my reference. My Vref is < VDDA.
I'd appreciate any advice.

I see your concern, but VREFH shares its pin with VDDAD (analogue supply). As VDDAD should be at same level as VDD, I don't advise you to change its level. You could choose another MCU with VREFH separated, like AZ60A...
