/**
* I/O slot of sdio slave:
* Slot 0: GPIO 6, 11, 7, 8, 9, 10.
* Slot 1: GPIO 14, 15, 2, 4, 12, 13 for CLK, CMD, D0, D1, D2, D3 respectively.
*
* @note 1: Only one peripheral for SDIO and only one slot can work at the same time.
* @note 2: Slot 0 is occupied by SPI for Flash, therefore we only use Slot 1
