The DIP Switch is labeled for bit number and '1' '0' in the silk screen. The DIP Switch
can be read from this port and used to determine which PMC Parallel TTL is which in a
system with multiple cards installed. The DIPswitch can also be used for other
purposes – software revision etc.
The Design ID and Revision are a 16 bit field allowing for 256 designs and 256 revisions
of each. The base design is 0x01 the current revision is 0x01. As new features are
added to the base design the revision will be updated to allow software to "know" which
features are present. When customer specific versions are done the design number will
be changed.
