In low speed mode, card clock must be lower than 400 kHz, voltage ranges from 2.7 to 3.6 V.
In normal data transfer mode for SD/SDIO card, clock frequency can be any value between 0 ~ 25 MHz.
In normal data transfer mode for MMC card, clock frequency can be any value between 0 ~ 20 MHz.
In card identification mode, card clock must be 100 kHz ~ 400 kHz, voltage ranges from 2.7 to 3.6 V.
Suggested ClockPeriod = T, CLK_DIVIDER (in SDHC Clock Rate Register) = D, then TH = [(D+1)/2]/(D+1)*T where []
