Arlington, Tex. -PC/104 bus, TTL-compatible, 96 point digital I/O interface includes interruptible event sense. This feature monitors both rising and falling digital edge transitions, latches them, and signals the host of the change of input status. Each I/O line is programmable for input, output, or output with read-back operation. Event sense is featured on 48 of the lines. Transition polarity is programmable and enabled on a bit-by-bit basis. An interrupt ID register is maintained for each line for writing more efficient Interrupt Service Routines.
