MSP432E401Y: Dynamic pin config change [MSP432P401R]

Conor

Part Number: MSP432E401Y

Hi,

1) Is it okay to make dynamic Pin config changes?

■ Specifically what I want to do
I would like to use the RX pin of UART as an input interrupt pin of GPIO and switch to UART for communication when an input interrupt comes.

■ Background of the question
In the past, there is a customer who designed the C5000 to dynamically operate the register that switches the internal bus.
Glitch occurred inside the device, and the data was garbled. So I'm wondering if MSP432 is the same.

2)The information of MSP432P4 has disappeared from the Web, and I could not create a new thread in E2E. Is the status of MSP432P4 NRND or EOL?

Thanks,

    Hi Koki,

    Regarding your questions,

    1. It should be possible to dynamically change pin functions on MSP432P. Here's a thread that discusses using the port mapper module to do so [link].

    2. MSP432P is NRND.

    Thanks,
