Encoding input for operation mode selection
(configuration of the receiver firmware).
The operation mode is defined at the first power-up
in accordance to the pin connecting. A later change
of the operation mode is possible at power-up, but
only if the ID memory is cleared in addition
(connect CLR-pin to GND -> power-down ->
change CODE-pin connecting -> power-up).
Resistor network input.
Code pins should be left
open or connected to
GND (for encoding
schematics, see chapter
