Detailed explanation-1: -Call an execution instruction. The program counter (PC) is a register that manages the memory address of the instruction to be executed next. The address specified by the PC will be + n (+1 for a 1-word instruction and +2 for a 2-word instruction) each time one instruction is executed.
Detailed explanation-2: -PC contribution stands for ‘Previous Charge’ contribution. You’ll see this on your top up receipts if part of your top-up is going towards an outstanding balance on your account. Your meter will be set to collect some of your arrears with each top up made, this won’t be more than 20% of each top up.
Detailed explanation-3: -The program counter is also called an instruction pointer or instruction address register.
Detailed explanation-4: -The program counter (PC) holds the address of the next instruction to be executed, while the instruction register (IR) holds the encoded instruction. Upon fetching the instruction, the program counter is incremented by one “address value” (to the location of the next instruction).
