Solved it but will leave up incase anyone else has issue because it's sort of strange.
It's not enough to enable the pullups you have to disable the pulldowns .. apparently you can have both on![:-)]( "Smile")
The other GPIOs pulldowns are obviously removed by start up system because they have other functions.
So the correct code turned out to be

Code:
IO_BANK0->GPIO3_CTRL_b.FUNCSEL = 3; // Select GPIO3 function PADS_BANK0_CLR->GPIO3_b.PDE = 1; // Pull down on GPIO3 disable PADS_BANK0_SET->GPIO3_b.PUE = 1; // Pullup GPIO3 enable IO_BANK0->GPIO2_CTRL_b.FUNCSEL = 3; // Select GPIO2 function 3 PADS_BANK0_CLR->GPIO2_b.PDE = 1; // Pull down on GPIO2 disable PADS_BANK0_SET->GPIO2_b.PUE = 1; // Pullup GPIO2 enableStatistics: Posted by LdB — Fri Jan 23, 2026 6:50 am
