preliminary
Warning output WARN can only be switched on at the
same time as the switching output and is reset as soon
as sufficient received light is detected.
The delay times are configured using parameters TAR
and TAF.

STARTUP BEHAVIOR, OPERATING MODES, AND STATUS REGISTER
Startup behavior and operating modes
After iC-LO has started up all internal registers and
counters are reset to 0. Switching outputs SO and
NSO are thus at 0. The warning output is activated.
The device waits for further commands (operating
mode STARTUP/RESET).
Implemented commands
By writing to address 0x0E commands can be exe-
cuted and the device operating mode changed.
