Z80 Assembly 62: Interfacing with the Z80 CTC (Counter/Timer Circuit)
The Role of the Z80 CTC The Z80 CTC (Counter/Timer Circuit) is a dedicated peripheral chip that provides four independent channels (Channel 0 to 3), each capable of acting as a counter or a timer. This chip is crucial for relieving the Z80 CPU of the burden of running software timing loops (Part 15). Advantage: The CTC allows for precise, hardware-based timing that operates in the background, freeing the CPU to run main program logic. ...
