Card Input Clock
SDHC Output/Card Inputs CMD, DAT (Reference to CLK)
SDHC Input/Card Outputs CMD, DAT (Reference to CLK)
In low speed mode, card clock must be lower than 400 kHz, voltage ranges from 2.7 V–3.3 V.
In normal data transfer mode for SD/SDIO card, clock frequency can be any value between 0 MHz–25 MHz.
In normal data transfer mode for MMC card, clock frequency can be any value between 0 MHz–20 MHz.
In card identification mode, card clock must be 100 kHz–400 kHz, voltage ranges from 2.7 V–3.3 V.
