TMS320F280040-Q1: GPIO23 as SCIBTx does not work

Part Number: TMS320F280040-Q1

Tool/software:

Hi everyone,

I am trying to use the GPIO23 as SICB TX, I configured it as GPIO_22_SCITXDB and disabled the analog default function, attached image, but I am not able to see the signal that I want to transmit by SCIB. I have done testing using another pin like GPIO_14_SCITXDB and it works.

Any suggestion?

Thanks
