Pad Weak Pull-Down Enable
Value Description
1 The corresponding pin has a weak pull-down resistor.
0 The corresponding pin is not affected.
Setting a bit in the GPIOPUR register clears the corresponding bit in
the GPIOPDR register. The change is effective on the second clock
cycle after the write if accessing GPIO via the APB memory aperture.
If using AHB access, the change is effective on the next clock cycle.
