I am using 89s52 microcontroller. While debugging the followin
part of program is not simulated. 

 
MOV R0,#80H 
MOV 80H,#55H 
MOV A,@R0 

 
Here I expect that the data 55h will be loaded in the Accumulator.
to load the data in 80h I am using following</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Indirect addressing</title><link>https://community.arm.com/thread/57468?ContentTypeID=1</link><pubDate>Fri, 18 Dec 2009 20:14:03 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:cc29eb2d-97c9-44d8-9d3c-7257e82212cc</guid><dc:creator>ashley madison</dc:creator><description>&lt;p&gt;&lt;p&gt;
