Notes:
1. This pin is not grounded on the Osprey since it can be used to detect the presence of an mSATA
module versus a Mini PCIe card.
2. This pin is not grounded on the Osprey to make it available for mSATA module detection.
3. This signal drives the blue LED activity indicator shown in
. This LED lights with mSATA
disk activity (if supported by the mSATA module).
4. Some Mini PCIe cards use this signal as a second Mini PCIe card wireless disable input. On the
Osprey, this signal is available for use for mSATA versus Mini PCIe card detection. There is an
option on the VersaLogic Features BIOS Setup utility screen for setting the mSATA detection
method.
W_Disable# Signal
The W_DISABLE# is for use with optional wireless Ethernet Mini PCIe cards. The signal
enables you to disable a wireless card’s radio operation in order to meet public safety regulations
or when otherwise desired. The W_DISABLE# signal is an active low signal that when driven
low (shorted to ground) disables radio operation on the Mini PCIe card wireless device. When
the W_DISABLE# is not asserted, or in a high impedance state, the radio may transmit if not
disabled by other means such as software. The W_DISABLE# signals for each of the two
Minicards are controlled by registers in the FPGA.
