Control interface (Signals)
The MC7710 provides signals for:
• Waking the host when specific events occur
• Power control of the module from the host
• LED driver output
These signals are summarized in Ta bl e 4-5 and paragraphs that follow.
WAKE_N — Wake host
The module uses WAKE_N to wake the host when specific events occur. (Support
for this signal is firmware dependent. Contact your Sierra Wireless account
representative to determine specific availability.)
The host must provide a 5 k–100 k pullup resistor that considers total line
capacitance (including parasitic capacitance) such that when
WAKE_N is
deasserted, the line will rise to 3.3
V in < 100 ns.
See Figure 4-5 on page 35 for a recommended implementation.
