3.9 Network Status Indication Interface
The C16QS module provides an open-drain GPIO signal to indicate the status of the RF communication.
3.9.1 Network Status
C16QS provides two network status indication pins: NET_STATUS (Pins 21 & 75). These pins are used to
drive a network status indication LED. Since both the pins have the same functionality, use only one and
keep the other floating.
The following tables describe the pin definition and logic level changes of NETLIGHT in different network
activity status.
