on the AS-i line
3.3.4. Master-, Repeater- and Monitor-Mode
In Master-, Repeater-, and Monitor-Mode the IRD input is always configured in CMOS mode. The input levels
specified in Table 12 apply.
The expected polarity of the Manchester-II-coded bit stream at the IRD pin depends on the values of the Pins
DI0 and DI1.

Note: The complemented definition was chosen to retain backward compatibility to A²SI based AS-i Master
designs.

pliant Universal AS-I IC
Description
Manchester-II-Signal is low active (default logic output value at no
communication is ‘1’). This mode is compatible to the A²SI IRD input
Manchester-II-Signal is high active (default logic output value at no
communication is ‘0’).
