You need to use the 'pre' tags for code formatting - not 'quote'
See: http://www.8052.com/faqs.phtml?FAQ=120199 Shruthi Kumar said:
MSG_D = 03; while( !( ReadRegister( MSG_D ) & 08 ) ); MSG_E = 4;does this mean that that the control comes out of the loop to "MSG_E =4;" if the value "ReadRegister( MSG_D ) & 08" is = 11110111b Why would it mean that? Where does 11110111b come from? The while is a standard 'C' construct that works the same on all targets - this has nothing specifically to do with 8051s! The general form is: while( <condition> ) <statement> ;This means that <statement> will be repeated so long as <condition> is True. In 'C', "True" means "non-zero" |
