Signal Description
Reset signal from host. Reset is active on power
up and inactive thereafter.
Ground
Pins 3 through 18 (16 lines (15-0) carry the data
between the controller and the host. The low 8
lines transfer commands and the ECC
information between the host and the controller.
Ground
No connection. Reserved for connector key.
Not used.
Ground
This I/O Write strobe pulse is used to clock I/O
data or commands on the drive data bus into the
drive controller registers when the drive is
configured to use the I/O interface. The clocking
will occur on the negative to positive edge of the
signal (trailing edge.
Ground
This is a Read strobe generated by the host. The
signal gates I/O data or status on the host bus
and strobes the data from the controller into the
host on the low to high transition (trailing edge).
Ground
Not used. Pulled up to Vcc through a 4.7k ohm
resistor.
