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