7.3 Signal Loading
The total capacitance CL is the sum of the bus master capacitance CHOST, the bus capacitance CBUS, and the
capacitance CCARD of the card connected to the line:
CL = CHOST + CBUS + CCARD
To allow the sum of the host and bus capacitances to be up to 20pF for the card, the following conditions in the
table below are met by the card.
