Page 23: Wake# Signal
No.: 1) is an output signal, active low level or low fall edge. This signal is a reserved signal for ZM8620 to wake up the system host. ZM8620 pulls up the power level to VDD_3V3 internally by the 10Kohm resistance. It is recommended to connect the 47ohm resistance to the GPIO PIN on the main chip (If this GPIO PIN is on the system side, it can wake up the host). -
