Problem 3 1. If the Program Counter (PC) in a Von Neumann microcontroller is a 20-bit register, what can you conclude about the addressable memory space of the microcontroller? 2. Assuming the microcontroller has Harvard architecture, what can you conclude about the maximum size of the memory code? 3. If the instruction size of this microcontroller is 4 bytes, show that the two least significant bits of PC are always 0. Problem 3 1.
