OSPEED3=B_0x0
GPIO port H output speed register
OSPEED3 | Port H configuration I/O pin 3 These bits are written by software to configure the I/O output speed. Access can be protected by GPIOH SEC3. Note: Refer to the device datasheet for the frequency specifications and the power supply and load conditions for each speed. 0 (B_0x0): Low speed 1 (B_0x1): Medium speed 2 (B_0x2): High speed |
