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
As described in
, 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

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.
