When operating in CF Advanced timing modes, the host shall conform to the following requirements:

1)Only one CF device shall be attached to the CF Bus.

2)The host shall not present a load of more than 40pF to the device for all signals, including any cabling.

3)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.

4)The -WAIT and IORDY signals shall be ignored by the host.

Devices supporting CF Advanced timing modes shall also support slower timing modes, to ensure operability with systems that do not support CF Advanced timing modes
