[MKW01] LPTMR internal pullup

Hello, i'm using the LPTMR as a pulse counter, but the internal pull-up is not working in this mode.

The pin I'm using is the PTE17 - ALT6 (LPTMR0_ALT3), and the pullup works fine as a GPIO, but when I change the mux to ALT6 the pin goes floating.

Here's the code:


      PORT_HAL_SetMuxMode(PORTE,17u,kPortMuxAlt6);           /* PTE17 - ALT6 */


With an external pullup it works fine, but I need to use the internal for my hardware.

Thanks in advance.
