1.12 Mini PCIe specific signals (W_DISABLE#, LED_WWAN#)
Mini PCI Express specific signals (W_DISABLE#, LED_WWAN#) are not available on TOBY-L2 series.
MPCI-L2 series modules include the W_DISABLE# active-low input signal to disable the radio operations as
specified by the PCI Express Mini Card Electromechanical Specification [14].
As described in Figure 20, the W_DISABLE# input is equipped with an internal pull-up to the 3.3Vaux supply.
The W_DISABLE# input detailed electrical characteristics are described in the MPCI-L2 series Data Sheet [2].

Figure 20: MPCI-L2 series modules W_DISABLE# input circuit description
MPCI-L2 series modules include the LED_WWAN# active-low open drain output to provide the Wireless Wide
Area Network status indication as specified by the PCI Express Mini Card Electromechanical Specification [14].
For more electrical characteristics details see the MPCI-L2 Data Sheet [2].
1.13 Reserved pins (RSVD)
Pins reserved for future use, marked as RSVD, are not available on MPCI-L2 series.
TOBY-L2 series modules have pins reserved for future use, marked as RSVD: they can all be left unconnected on
the application board, except the RSVD pin number 6 that must be externally connected to ground.
1.14 Not connected pins (NC)
Pins internally not connected, marked as NC, are not available on TOBY-L2 series.
MPCI-L2 series modules have pins internally not connected, marked as NC: they can be left unconnected or they
can be connected on the application board according to any application requirement, given that none function is
provided by the modules over these pins.
