Interrupts
The Z8536 is programmable to generate interrupts based on bit change, pattern recognition, level or edge
triggered, whether configured as a digital I/O port or counter port. Refer to the ZILOG Z8036/Z8536 ProductSpecification for further options. This document is available on our web site atwww.mccdaq.com/PDFmanuals/Z8536.pdf.

Interrupt priority

INTA# - mapped to IRQn via PCI BIOS at boot-time
Programmable (enabled by default) and external (INT ENABLE), active low(pulled high through resistor).
Programmable: 8536A interrupt output, 8536B interrupt output, 8536A OR'ed with
8536B, external (INT INPUT, active low) or None.
Buffered output for each chip available at user connector (INTA OUT, INTB OUT).
Programmable: No priority or 8536A interrupt has priority over 8536B interrupt.
