2.6 WAKE-UP
The WAKEUP input pin wakes the RN4678 module
from Deep-Sleep mode. The WAKEUP pin is active-
low and puts module in Standby mode.
Figure 2-5
illustrates the timing diagram of the RN4678 in the
Wake-Up mode.

Note 1: The 85 ms is for reference time. Use the Status Indication pins to verify the exact results.
2.7 External Reset
The RN4678 provides an External Reset pin which
resets the module. The Reset pin, RST_N, is active-
low. Figure 2-6 shows the timing diagram for the
RST_N pin of the RN4678 module.
