"ATX" memory space in MPC5777C

[ricardofranca]

Hello,

While looking at the MPC5777C peripheral bridge memory maps (in the MCU reference manual), I noticed 0xFFFF_0000 is reserved to "ATX" but the manual does not provide a meaning for this. What is it supposed to be?

Thanks,

Ricardo

Hello,

Here is the answer from application team:

an internal chip test feature for NXP test engineering.  Should really not be visible to customers in the memory map but it looks like that was never caught in review.

Best regards,

Peter

Hello,

I see it is some kind of ADC  module for sensing of 5V.

I need to ask internally for clarification as this module is not described anywhere I can see.

I will come back to you ASAP.

best regards,

Peter
