About this document
82C55A Interface and Interrupt Handling by Vivek Roy is a document available to read on EtoBox.
The document discusses interrupt handling on an 8085 microprocessor system. It describes using the RST7.5 interrupt input to read a switch and energize a relay coil for one second by driving the coil with the SOD line whenever the switch is pressed. It also discusses using a D-type latch circuit with the interrupting source at the clock input to hold the interrupt request, and clearing the latch output using the SOD line after processor acknowledgement. An assembly language program is shown to implement thi
