WebJan 29, 2010 · The 8080 has an Interrupt line (pin 14). All peripherals are wired to this pin, usually in a "wire-OR" configuration (meaning interrupt request outputs are open-collector and the interrupt pin is pulled high with a resistor). Internally, the processor has an Interrupt Enable bit. Two instructions, EI and DI, set and clear this bit. WebMay 5, 2024 · Connect RX-Pin with another Input-Pin. For that Pin you get an attached interrupt with the start of a new incomming data byte. Do not forget to disable that interrupt until the character has received completly.
