Additional Details

The Z0843004CME CTC typically operates at a clock frequency of 4 MHz. Each of the four channels can be independently programmed to operate as a timer or a counter. In timer mode, the channel generates an interrupt after a specified time interval. In counter mode, the channel counts external events and generates an interrupt after a specified number of events. The CTC can be interfaced to the Z80 CPU using standard memory-mapped I/O techniques.
