Final answer:
A register-based programmed timing function retains its accumulated value between input signals.
Step-by-step explanation:
A register based programmed timing function retains its accumulated value between input signals. In computer programming, a register is a small amount of storage inside the CPU that holds data that can be quickly accessed by the processor. When a timing function is programmed to use a register, the current value of the timing function will be stored in the register and can be accessed and updated by the program whenever input signals are received.
