Introduction
This chapter describes the PC-TIO-10, lists the contents of your PC-TIO-10 kit, lists the optional
software and equipment for use with the PC-TIO-10, and explains how to unpack the PC-TIO-10
kit.
The PC-TIO-10 is a timing and digital I/O interface for the PC. Two AMD Am9513A STCs are
used for the timing interface. With these chips, which feature many different timing and
counting modes, the PC-TIO-10 can perform of a wide range of pulse measurement and wave
generation functions. A Motorola MC6821 PIA is used for the digital I/O interface; each of the
two 8-bit I/O ports is bit-configurable. In addition, the PC-TIO-10 has two edge-sensitive
interrupt inputs with programmable edge selection. Any external TTL signal, including any of
the counter outputs, can be connected to these interrupt inputs.
Figure 1-1 shows the PC-TIO-10 interface board.
