2.4. Master Mode
Master Mode and the related Repeater- and Monitor-Modes differ completely in their functional properties
from the Slave Mode. While the IC can autonomously perform different tasks in Slave Mode, it will only act as
physical layer transceiver in Master-, Repeater- and Monitor-Mode. The basic property of these modes is a
modulation / demodulation of AS-i signals to Manchester-II-code and vice versa. The following figure shows
the different data path configurations.
Master-Mode, Repeater-Mode and Monitor-Mode differ from each other in the kind of signals that are
available at the data I/O and parameter port pins of the IC. Following signal assignments are provided:
More detailed signal descriptions can be found in chapters 3.6 Parameter Port and PST, 3.7 Data Port and
DSR as well as 3.12 UART.

Inverting of IRD input signal. If both inputs are on different level, the IRD input signal is inverted
before further processing, otherwise it is directly forwarded to the UART.
Inverting of LED output signal. If both inputs are on different level, the LED output signal is in-
verted after processing, otherwise it is directly forwarded to the LED1 output.
