extp#37h,#1 mov r12, 3A0Bh what will be the value of r12? will it be 1? yes!
The value will be 1 (which is on the right column of debugger) or will it be the hex value on the left side column of the debugger?
From Menu Button Text patch:
27E97A: E6 FC 06 3A : mov r12, #3A06h
27E97E: E6 FD 37 00 : mov r13, #37h
this is what i was asking about Prof. Isnt 37h:3A06h a RAM location? so r12 and r13 were assigned with their corresponding values above. What happens to their values? op1 can be 1to4
so this means we can use extp #37h, #4, which correspond to 4x use of it? |
