Reset Description
0x0000.00 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.
0x00 Pad Weak Pull-Down Enable
Value Description
0 The corresponding pin's weak pull-down resistor is disabled.
1 The corresponding pin's weak pull-down resistor is enabled.
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.
