Chapter 4

Programming

This chapter discusses the programming of the AT-MIO-16D. Included in this chapter are the
AT-MIO-16D register address map, a detailed register description, and a functional
programming description.
Note: If you plan to use a programming software package such as NI-DAQ for DOS/Windows
or LabWindows with your AT-MIO-16D board, you need not read this chapter.
However, you will gain added insight into your AT-MIO-16D board by reading this
chapter.

Register Map

The register map for the AT-MIO-16D is shown in Table 4-1. This table gives the register name,
the register offset address, the size of the register in bits, and the type of the register (read-only,
write-only, or read-and-write). The actual register address is computed by adding the individual
offset address to the board base address.
