TMD4903 − Application Information

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 Logical Block

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.
