19.5 AT^SLED LED Feature
AT^SLED controls the LED function provided by the EHS6's STATUS pin, which acts as an output and can be
used to control a connected LED.
The AT^SLED command is functional only if LED functionality is enabled with AT^SCFG="Gpio/mode/SYNC" set
to "std". The electrical specifications of the status pin and advice on how to connect the LED circuit can be found
in [2]. The LED indicates the operating states listed below:
