Suppose the LC-3 datapath allows combining the two registers into one. Using separate registers, the test to see if the Ready bit is set simply involves checking bit 15 of the status register. This is performed using a branch instruction that tests if the value of the register is negative. If the KBSR and DSR are combined, the test to see if the Display device Ready bit is set involves masking out bit 14 and testing if the bit is set or cleared. Doing it this way requires more instructions than the first method
