The total capacitance C L is the sum of the bus master capacitance C HOST , the bus capacitance C BUS ,
and the capacitance C CARD of the card connected to the line:
C L = C HOST + C BUS + C CARD
To allow the sum of the host and bus capacitances to be up to 20pF for the card, the following conditions
in Table 11 are met by the card.
