Chapter 4 Register-Level Programming

There are two interrupt control registers on the PC-DIO-96. One of these registers has individual

enable bits for the two interrupt lines from each of the 82C55A devices. The other register has a

master interrupt enable bit and two bits for the timed interrupt circuitry. Of the latter two bits,

one bit enables counter interrupts, while the other selects counter 0 or counter 1. The bit maps

and signal definitions are listed as follows.

1 2 ... 38 39 40 41 42 43 44 45 46 47 48 ... 104 105
