Usage

To configure the pin multiplexing function, follow the steps below:

1. Turn off the SWD or enable audio pad share if the pin default function is SWD or audio, and configure it to other functions.

   Pinmux_Swdoff();
   HAL_WRITE32(PINMUX_REG_BASE, REG_PAD_AUD_PAD_CTRL, 0x1FFFFF);
   

2. Turn off the SWD if the pin default function is SWD, and configure it to other functions.

   Pinmux_Swdoff();
   

3. Configure pinmux function.

   Pinmux_Config(u8 PinName, u32 PinFunc);
   

4. Set pin pull type.

   PAD_PullCtrl(u8 PinName, u8 PullType); //normal mode
   PAD_SleepPullCtrl(u8 PinName, u8 PullType); //sleep and deep-sleep mode
   

5. Set driving strength if needed.

   PAD_DrvStrength(u8 PinName, u32 DrvStrength);
