Detailed Description

Configuration structure for initializing an SD card handle.

Passed to sd_init_handle to configure the SPI peripheral and all four SPI GPIO pins (SCLK, CS, MISO, MOSI) connected to the SD card.

Note: The CS pin is configured as a GPIO output and driven manually. SCLK, MISO, and MOSI are configured in alternate function mode.
