DESCRIPTION
Signal Ground
These are intended to provide isolation for the high speed differential signals.
SATA Differential
The functionality and electrical characteristics of these pins are defined in the

DESCRIPTION
CMOS Input
CMOS Output
LED Output
This signal is driven by the CFast host, and shall be sampled by the CFast
device
This pin shall be shorted on a CFast device to CDO.
This signal and CDO provide a mechanism for a CFast host to detect that a
CFast device has been fully inserted, and so that power can be applied safely.
The host may drive, and the device may sample, this pin to provide signaling
to enable CFast Power Management Sleep state.
This pin shall be shorted on the CFast device to CDI. It is effectively driven
by CDI.
