Strap Configuration
I/O Write. Active (low) level indicates I/O write cycle on the X-Bus
Extension. This signal is for devices that require separate
read/write inputs for memory and I/O.
Data Bus
Address Bus
Chip Select. These signals control the selection of up to two
chips residing on the X-Bus Extension.
Assert Strobe. These signals control the selection of up to three
external latch devices for X-Bus Latched Address Mode
transactions.
I/O Ready. This signal indicates to the PC87393 to extend the
access cycles.
Parallel Interrupt. Convert parallel interrupts into serial interrupts
by means of the Interrupt Serializer (The interrupt number
associated with each signal is a part of the system configuration.)
