When designing a 4-bit microcomputer from TTL ICs, you decide to incorporate the following instructions: LDA data, STA data, HLT, ADD data, SUB data. JMP address and INA (increment accumulator). To minimize the complexity, you want to use a program counter IC which has only those capabilities absolutely necessary to run a program beginning at memory location 0000. Which of the following functions would NOT be required by the program counter in the microcomputer?

1) increment program counter (3) clear program counter 2) decrement program counter (4) parallel load program counter
