2-18 Module Operation
In this example, four ranges are specified. Configuration data for the
counter is shown in the table. It indicates that output 0 is on for
counts within range 1, output 1 is on for counts within range 2, output
2 is on for counts within range 3, and both outputs 0 and 3 are on for
counts within range 4. When the count is 2000, outputs 2 and 1 are
on, since 2000 falls within ranges 2 and 3.
The figure below demonstrates Range Mode when a ring counter is
used.
