Does anyone know how I could disable the UART0 in pins (PTB1 and PTB2). I need to disable the UART0 entirely to go into LLS mode so that is very little current consumption.This is in the Frdm KL05Z board.
If you add an internal pull-up to the UART Rx it should give you lowest power consumption (to avoid floating). Driving an output in LLS mode should not be an issue.

It works, Thank you
