Note that the total capacitance of CMD and DAT lines will be consist of C
connected separately to the SD Memory Card host.
Host should consider total bus capacitance for each signal as the sum of C
defined by per signal. The host can determine C
capacitance load (CL=40 pF). The SD Memory Card guarantees its bus timing when total bus capacitance is less than
maximum value of CL (40 pF).
