CHAPTER 3
PROGRAMMING DETAILS
This chapter provides details of the cards internal registers.
Address Map
The address map for the PCI-DIO occupies a 12-byte block of addresses.
All the following addresses are relative to PCI base address register 2, located at
address 18 (hex) in the PCI configuration space.

Digital Outputs
By writing a byte or word to the Data Output Buffer (word write to base + 4),
the digital outputs may be controlled. A logic 1 written to the register causes the
open collector output to turn on, and pull the output low. Consequently there is
a logic inversion through the digital outputs of the card.
Bit 0 (LSbit) of the Data Output Buffer controls Digital Output 1, and bit 15
(MSbit) controls Digital Output 16.
It should be noted that there is a latency of 2.4 mS between writing to the
output buffer and the output changing state.
