The API CyU3PSibSendSwitchCommand 's second parameter uint32_t argument is written to SDMMC_CMD_ARG0 register. You can refer to section 10.26.6 of the FX3 TRM
The SDMMC_CMD_ARG0 register holds the lower 32 bits of the SD/MMC/SDIO command argument. Any additional argument bits for expanded command may be placed in the SDMMC_CMD_ARG1 register. There are two copies of this register corresponding to the two storage ports
Brilliant thank you!
