TMD4903 − Application Information
Figure 78:
Pattern Generation by Logical Block
The digital logic in the remote control engine has been tailored
to fit the data format and protocol specifications for IR remote
control. “Press and Release” type buttons (E.g. Power) are
generated using the logic in the red box. “Press and Hold” type
buttons (E.g. Volume+) are generated using logic in both the
red and blue boxes. Figure 78 depicts how a command pattern
with a repeated sub-pattern is created using the logic shown in
the Simplified Flow Diagram. All of the “run-once” sub-pattern
and the “first” instance of the “repeated” sub-pattern is actually
run by the logic in the red box. The second instance of the
“repeated” sub-pattern is run by the logic in the blue box.
Pattern Generation by
Digital Logic Block
First of Repeat part
Second of Repeat part
Generated by “red box logic”
“Complete” Pattern
Generated by “blue box logic”
Pattern Generation: All of the “one-time” sub-pattern and the “first” instance of the “repeated” sub-pattern is
actually run by the logic in the red box. The second instance of the “repeated” sub-pattern is run by the logic in
the blue box.
