### AX58100 SPI Configuration and Usage

For configuring the AX58100 with STM32F103 as an EtherCAT slave using SPI interface, specific GPIOs need to be configured properly. The SPI1 is chosen for communication purposes where PA4 serves as the Chip Select (CS) pin but remains uninitialized within CubeMX; instead, it gets added directly into the program code[^1].

To interact effectively via SPI protocol between STM32 microcontroller and AX58100 Ethernet PHY device:

#### Initialization of SPI Interface on STM32
The initialization process involves setting up the necessary parameters such as baud rate, data frame format, etc., which can typically be done through HAL libraries provided by STMicroelectronics or manually coding register values.

// Example setup function for initializing SPI peripheral.
void MX_SPI1_Init(void){
    hspi1.Instance = SPI1;
    hspi1.Init.Mode = SPI_MODE_MASTER;
    hspi1.Init.Direction = SPI_DIRECTION_2LINES;
    hspi1.Init.DataSize = SPI_DATASIZE_8BIT;
    hspi1.Init.CLKPolarity = SPI_POLARITY_LOW;
    hspi1.Init.CLKPhase = SPI_PHASE_1EDGE;
    hspi1.Init.NSS = SPI_NSS_SOFT;
    hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_16;
    hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;
    hspi1.Init.TIMode = SPI_TIMODE_DISABLE;
    hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
    if (HAL_SPI_Init(&hspi1) != HAL_OK){
        Error_Handler();
    }
}

This example demonstrates how one might set up a master mode SPI connection suitable for communicating with devices like AX58100 over SPI bus. Note that this snippet does not cover all aspects related specifically to AX58100 configuration beyond basic SPI settings.

#### Communicating With AX58100 Over SPI Bus
When sending commands or reading status from/to AX58100, synchronous (`spi_sync`) functions are generally preferred due to their simplicity compared to asynchronous operations when dealing with embedded systems programming tasks involving direct hardware interaction at low levels[^2]. However, both methods require constructing appropriate `spi_message` structures containing transfer details before invoking these APIs.
