Specification
Control Interface (Signals)
The EM7411 provides signals for:
•
Waking the host when specific events occur
•
Host control of the module’s radios
•
Host control of module power
•
LED driver output
Note: Host support for Full_Card_Power_Off# is required, and support for other signals in Table 2-5
is optional.
These signals are summarized in Table 2-5 and paragraphs that follow.

WAKE_ON_WAN# — Wake Host
Note: Host support for WAKE_ON_WAN# is optional.
The EM7411 uses WAKE_ON_WAN# to wake the host when specific events occur.
The host must provide a 5 kΩ–100 kΩ pullup resistor that considers total line capacitance
(including parasitic capacitance) such that when
WAKE_ON_WAN# is deasserted, the line
will rise to 3.7 V (Host power rail) in < 100 ns.
See Figure 2-7 on page 31 for a recommended implementation.
