Issue with W7500P Peripheral Example - WZTOE

Question

Hi, I found at the example of W7500P - WZTOE , still Use PB_14 and PB_15 for MDIO, but W7500P datasheet and Reference manual do not define these two pins, which exist only at W7500, I hope to get help for this issue. Thanks, Ed

I only looked at examples of DHCPClient and LoopbackTest.

At the example of WZTOE_DHCPClient: mdio_init(GPIOB, MDC, MDIO ) is called by main(). The following code are from subroutine mdio_init(): PAD_AFConfig(PAD_PB, GPIO_Pin_MDIO, PAD_AF1); // GPIO_Pin_MDIO = GPIO_Pin_15 PAD_AFConfig(PAD_PB, GPIO_Pin_MDC, PAD_AF1); // GPIO_Pin_MDC = GPIO_Pin_14 But when I refer to datasheet and reference manual of W7500P, which do not define the alternate funtion of PB_14 and PB_15 Pin. The following code also are from main(), I could n’t find the definition of pad control register with address of (0x41003070) and (0x41003054). ifdef W7500P *(volatile uint32_t *)(0x41003070) = 0x61; *(volatile uint32_t *)(0x41003054) = 0x61; #endif So, I hope to get support and advice, Please!!!
