9.2.1 GPIO Pullup Enable Register (GPIOx_PUR)
This register is for internal pullup enabling and disabling. If the pin is configured as an
output, this register is not used. This register is read and write. Unimplemented bits read
as 0.
The pullup is intended only to drive an undriven input pin to a known state. It is
characteristically a very weak pullup.
Addresses: GPIOA_PUR – F140h base + 0h offset = F140h
