Z80 I/O Space
A very interesting feature of the Z80 microprocessor is that it has separate memory and I/O space. Separated memory and I/O space means that instead of having to treat your peripherals as a memory address in between your other actual … Continue reading
Z80 Interrupts
The Z80 microprocessor supports three interrupts modes; 0, 1, and 2. In interrupt mode 0 the Z80 gets an instruction from the data bus given by the peripheral and executes it. This instruction is normally RST0 -> RST7 which resets … Continue reading
Z80 Memory Space
Memory is the fuel of a system. The memory is where instructions and data are stored. There are many types of memory, but for simplicity we will specifically be considering parallel ROM and RAM devices.
Z80 External Hardware Model
The Z80 Microprocessor is an 8-bit microprocessor that comes in many package types and has 40 usable pins. These pins make up the power, address bus, data bus, control signals, and clock that run a system. There are 2 power … Continue reading
Z80 Journal
This journal will randomly document things I have learned about the Z80 Microprocessor as I either learn or are am interested in them. I hope to randomly aggregate material and present it as a boiled down version of the topic … Continue reading
