ID
In low-speed mode, the card clock must be lower than 400 kHz, voltage ranges from 2.7 to 3.6 V.
In normal-speed mode for the SD/SDIO card, clock frequency can be any value between 0–25 MHz. In high-speed mode,
clock frequency can be any value between 0–50 MHz.
In normal-speed mode for MMC card, clock frequency can be any value between 0 and 20 MHz. In high-speed mode, clock
frequency can be any value between 0–52 MHz.
To satisfy hold timing, the delay difference between clock input and cmd/data input must not exceed 2 ns.
