Write a "bit pattern" output routine that prints to the console the value stored in a register (say R2) as a 16-bit binary number. So if R2 contains the value x1234, then the o/p would be just: b0001 0010 0011 0100 i.e. the ascii symbols for ‘b’ followed by the appropriate sequence of 1's and 0's (the space separating groups of 4 bits is optional, but the initial ‘b’ is required). For this exercise, you can have the program itself set up the register with the value to be output: LD R2, number ;set up R2 with stored value ... HALT number .FILL x1234 ;hard coded value
