D.1 Digital I/O Card Channel Layout
The Digital I/O Card layout is complicated by the standard Rabbit method of minimizing
chip layout while adding channel arrangement flexibility. In particular, the nibble-wise
layout of digital input channels requires fewer chips if fewer channels are desired. This is
a common feature on Rabbit products and should not surprise most users. The digital out-
put channel layout is straightforward.
It is also possible to access the digital I/O channels in banks of eight channels. This
method is significantly faster than reading eight channels one at a time, and so was
included in the function call.
