*) Device Activity Pin is low in idle mode and high (flickering) during data transfer.
It can be optional disconnected on the module or the pin can configured without driving,
only pull up resistor on request.
In firmware revision “1” (part number -216-STD) this pin is driven low and high If this pin is grounded
by the host, a current goes through this pin.
In firmware “2” and higher this pin is only driven low as optional specified in the SATA -Specification
“SerialATA_Revision_3_0_Gold”
**) In standard products pin50 is not connected on the SSD to prevent power short circuit if connected to an
eeePC card connector, but could be optional connected to GND
