Answer to Question #245449 in Electrical Engineering for vibs

Question

IF PC= 682 , AR=123 , DR=A2BF, IR= 5672, then execute the following M[AR] DR IR M[AR] Determine the value of IR after the execution and comment on the type of addressing.

Answer 1

The remote control programming applications IR.exe and RMIR pass signals learned by a UEI remote that has itself performed a partial analysis of the signal. The data is passed in a structured form, divided into Once, Repeat and Extra sections.

A totally unrelated IR signal can accidentally fit the pattern of such a protocol resulting in a spurious decode. When you get a decode for a non-robust protocol you need to exercise some judgment about whether to believe or ignore that decode. Usually you can decide based on decodes of other signals of the same device.
