uPD71059C - Interrupt Control Unit, DIP28

Description
The pPD71059 is a low—power CMOS programmable
interrupt control unit for microcomputer systems. It
can process eight interrupt request inputs, allocating a
priority level to each one. It transfers the interrupt with
the highest priority to the CPU, along with interrupt
address information. By cascading up to eight slave
yPD71059s to a master pPD71059, a system can
process up to 64 interrupt requests. System scale,
interrupt routine address, interrupt request priority,
and masking are all under complete program control.
