In Master-, Repeater- and Monitor Mode the data input and data output ports are differently configured than in
Slave Mode. Following control signals are provided at the data input port in Master-, Repeater- and Monitor
Mode:
Table 24: Control signal inputs in Master-, Repeater- and Monitor Mode
Note: The complemented definition was chosen to retain backward compatibility to A²SI based AS-i Master
designs.
The Data Output Port is exclusively used in Monitor Mode to provide additional UART error signals. The
signals are defined active low and will be set immediately after a telegram error was detected. They become
reset at the beginning of the next telegram. Following signals are available:
Table 25: Error signal outputs in Monitor Mode
3.7.8.
Besides of its standard output function the Data Strobe Pin serves as external reset input for all operational
modes of the IC. Pulling the DSR pin LOW for more than a minimum reset time generates an unconditioned
reset of the IC, which is immediately followed by a re-initialization of the IC (E²PROM read out).
Further information on the IC reset behavior, especially in regard to the signal timing, can be found at chapter
3.11 IC Reset.

Description
If the signals invert_ird_a and invert_ird_b are unequal, the IRD
input signal is inverted before further processing. See Table 13.
If the signals invert_led1_a and invert_led1_b are unequal, the LED1
output signal is inverted after processing. See Table 28.

Data_Exchange_Disable
Indicates faulty AS-i pulses. This is a
disjunction of alternation error, start bit error,
end bit error
The output signal is a disjunction of
No_Information_Error and Length_Error as
defined in the Complete Spec 3.0.
The Monitor Mode does not distinguish
between synchronized and not synchronized
UART Mode. There is always only one bit
time supervised after the end of a telegram.
