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).
