MSPM0G1507: How to disable BSL PA18 pin and use for general purpose operation

MSPM0G1507: BSL Pin (PA18) reconfiguration

Tool/software:

Hi TI,

     We're using PA18 as ADC input channel. Later after certain conditions are met we're trying re-configure it as GPIO using as output pin with Pushpull configuration. All the logic is passing and I see the registers are also getting configured(DOUT31_0 and DOE31_0 are getting updated) but I don't see the output on the logic analyzer according to the my logic pattern.

Suggest me if I'm handling it wrong.

    Hi Manik,

    Are you testing the LP or your own board? We have the external pull down resistor in the LP.

    ADC input chennel will not imapct the GPIO output, they are seperatey configured and has seperately input/output path to the IO PIN.

    What the external hardware connection in PA18?

    B.R.
