DescriptionResetTypeNameBit/Field
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Pad Weak Pull-Up Enable
DescriptionValue
The corresponding pin's weak pull-up resistor is disabled.0
The corresponding pin's weak pull-up resistor is enabled.1
Setting a bit in the GPIOPDR register clears the corresponding bit in
the GPIOPUR 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.
The reset value for this register is 0x0000.0000 for GPIO ports that are
not listed in Table 9-1 on page 409.
