MKE18F512VLL16 : Internal Reference voltage for ADC and change the Package

[Ruthrapathy_K]

Hello,

I am using TWR-KE18F board for my development. I have 2 queries as follows

1. How can I change the ADC's reference voltage to Internal reference and how much is the voltage? In the reference manual it is given as "The alternate VALTH voltage reference may
select additional external pin or internal source depending on MCU configuration. See
the chip configuration information for the voltage references specific to this MCU". But I couldn't find anything in the Datasheet.

2. Now I am developing in MKE18F512VLL16(100 pin package) MCU and I want to change it to MKE18F512VLH16(64 pin package). How can I do that?

1. My guess is that the alternate voltage reference is not available, and it is kept in the documentation. Let me confirm this internally, and I will come back when I receive an answer.

2. It needs a re-design as the pins have different muxes between the packages.

BR,
Omar
