3.2.3 Board Map
The board map shown in
Figure 3.4
identifies the cell placement for each of the I/O pins. Each rectangle
labeled “Jx PIN y” starts as an unconfigured cell before a circuit is selected and placed on it, causing it to
become a configured cell.

Digital I/O is routed to a digital interface cell, which is routed to the core module. Analog inputs are routed
to an analog input interface cell, which is also routed to the core module. An analog input cell takes in the
ramp generator output, the eight possible analog inputs and three selector pins. A background process con-
tinually reads the analog inputs and stores the last values read.
