Q2. Consider a service routine that responds to a timer interrupt. Assume that the function of this service routine is simply to increment the current value of"clock"- an integer stored in absolute address CLOCK Ignore any overflow that may arise from this operation. Below is a pseudo code for this service routine. Pseudo code of the service routine Load CLOCK, R1* loads the integer stored in address CLOCK to register R1) INCREMENT R1 by 1 STORE R1, CLOCK (* stores the value in R1 to the memory location CLOCK*) RETURN (*Pops the return address from control stack and loads it to PC ) Questions: (a) Point out any problems with this code, in less than 30 words (b) Show a corrected pseudo code
