Bus Signal Line Load
The total capacitance CL of each line of the MultiMediaCard bus is the sum of the bus master capacitance
CHOST, the bus capacitance CBUS itself and the capacitance CCARD of each card connected to this line:
= + + CL CHOST CBUS N*CCARD
where N is the number of connected cards. Requiring the sum of the host and bus capacitance’s not to
exceed 30 pF for up to 10 cards, and 40 pF for up to 30 cards, the following values must not be exceeded:
