7) Address Signals: each card shall present a load of no more than 100pF
8) Data Signals: the host and each card shall present a load no larger than 50pF
9) Reset Signal: This signal is pulled up to prevent the input from floating when a CFA to PCMCIA adapter is used
10) Host and card restrictions for CF Advanced Timing Modes and Ultra DMA modes: Additional Requirements for
The CF Advanced Timing modes include PCMCIA I/O and Memory modes that are 100ns or faster and True
IDE PIO Modes 5,6 and Multiword DMA Modes 3,4.
When operating in CF Advanced timing modes, the host shall conform to the following requirements:

in a PCMCIA revision 1 host. However, to minimize DC current drain through the pull-up resistor in normal
operation the pull-up should be turned off once the Reset signal has been actively driven low by the host.
Consequently, the input is specified as an I2Z because the resistor is not necessarily detectable in the input
current leakage test.

Only one CF device shall be attached to the CF Bus.
The host shall not present a load of more than 40pF to the device for all signals, including any cabling.
The maximum cable length is 0.15 m (6 in). The cable length is measured from the card connector to the host
controller. 0.46 m (18 in) cables are not supported.
