Interrupt controller for Z80

ZEN1020P is a programmable interrupt control IC for Z80 and is around the Z80 CPU. It is used as an element.
ZEN1020P supports mode 2 interrupts up to 8 factors. Interrupt mask, Kuta address specification is controlled by the program, and the occurrence of an interrupt cause can be detected at the edge or checked.
You can also select to detect with a bell. In addition, by forming a daisy chain, there are more factors.
It also supports squeeze control.
