WP7702 & DisableResistors()

Hi all,

I have WP7702 on MangOH red and I’ve tried to control pull up/down resistors on WP7702.

When checking current state via le_gpioPin22_GetPullUpDown() I got LE_GPIOPIN22_PULL_DOWN state.
If I call le_gpioPin22_DisableResistors() it returns -20 (Unimplemented functionality). It is the same for other 7 CF3 available GPIOs (IoT0 & Pi).
Could someone confirm that this is the case, i.e. not implemented or is it a lack of support in WP7702 hw?
