Instructions
Power Supply:
- Connect the Vcc pin (pin 40) to a 5V supply.
- Connect the GND pin (pin 20) to ground.
Clock Configuration:
- Connect an external crystal or oscillator to the XTAL1 (pin 9) and XTAL2 (pin 10) pins for clock generation.
- Alternatively, use an external clock source connected to the XTAL1 pin.
Reset:
- Apply a reset signal to the RESET pin (pin 39) to initialize the CPU. The reset signal should be active low and held for at least 2 clock cycles.
Memory Mapping:
- Configure the address lines (A0-A15) to interface with external memory.
- Connect the data lines (D0-D7) to the external memory data bus.
I/O Ports:
- Use the I/O port control signals (IORQ, M1, RD, WR) to manage data transfer between the CPU and peripheral devices.
Interrupt Handling:
- Connect interrupt sources to the INT (pin 19) and NMI (pin 38) pins.
- Implement interrupt service routines (ISRs) in your program to handle interrupts.
Serial Communication:
- Use the TXD (pin 31) and RXD (pin 32) pins for serial communication.
- Configure the serial communication parameters (baud rate, data format) in your program.
Programming:
- Write your program using the Z80 instruction set.
- Load the program into external memory or a programmable ROM.
Testing:
- Verify the operation of the CPU by running simple test programs.
- Monitor the status of the CPU using the ready (RDY) pin (pin 24) and wait state (WAIT) pin (pin 25).
Power Down:
- To reduce power consumption, use the HALT instruction to put the CPU into a low-power mode.
- Resume operation by applying an interrupt or reset signal.
For detailed technical specifications and application notes, refer to the official Z80CPU datasheet and user manual.
