LP-MSPM0L1306: 5V tolerant GPIO's?

Part Number: LP-MSPM0L1306
Other Parts Discussed in Thread: MSPM0L1306

Hi,

I read in the datasheet that the MSPM0L1306 has 2 5V tolerant GPIO's. So, can it read 5V analog gas sensor like MQ2?

    The 5V tolerant (Open Drain) pins are PA0/1. These pins have no Analog function [Ref datasheet (SLASEX5A) Table 6-1].

    This is also true in the G series and the C series. The TRM(s) don't say (one way or the other) whether there's a design-level conflict between 5V/OD and Analog on a single pin.
