Explain 8259 Pin Diagram.
The 8259A adds 8 vectored priority encoded interrupts to the microprocessor. It can be expanded to 64 interrupt requests by using one master 8259A and 8 slave units. CS and WR must be decoded. Other connections are direct to microprocessor. The pins D7 - D0: the bidirectional data connection, IR7 - IR0: Interrupt request, used to request an interrupt & connect to a slave in a system with multiple 8259A.
WR: Attaches to a write strobe signal (lower or upper into a 16 bit system) ,
RD: Attaches to the IORC signal,
INT: Attaches to the INTR pin on the microprocessor from the master and is Attached to a IR pin onto a slave and
INTA: Attaches to the INTA pin onto the microprocessor.
Within a system only the master INTA signal is attached
