20 pts] 2- Consider the internal structure of the pseudo-CPU discussed in class augmented with a single-port register file (i.e., only one register value can be read at a time) containing 32 8-bit registers (RO-R31) and a Stack Pointer (SP). Suppose the pseudo-CPU can be used to implement the AVR instruction ICALL (Indirect Call to Subroutine) with the format shown below: 10001 10101 00001 10011 ICALL pushes the return address onto the stack and jumps to the 16-bit target address...
