5.1

A/D Conversion

Before programming the PCI-9113A to perform the A/D conversion, you
should understand the following issues:
A/D conversion procedure
A/D signal source control
A/D trigger source control
A/D data transfer mode
Interrupt System (refer to section 5.2)
A/D data format
Note: Because some of the A/D data transfer modes will use the
system interrupt resource, the users have to understand the
interrupt system (section 5.2) in the same time.
