7.3.4 8-Bit Counters and Delay Generators (CNT/DLY)

The counters/delay generators are 8-bit, supporting counter data values from 1 to 255. For flexibility, the clock source for each of these macro-cells can be configured as the internal oscillator, a divided clock derived from an oscillator (OSC/4, /12, /24, /64, /4096), or an external clock source coming from the connection mux. There is also the option to chain from the output of the previous CNT/DLY macro-cell to implement longer counter/delay circuits. Note that the counter/delay macro-cell is rising edge triggered, that is the counter will increment/decrement on rising clock edges.

As a counter/delay (CNT/DLY) macro-cell, users may select from the following modes: delay, counter.

DLY3 also has an optional edge detector that will generate a short pulse on the specified edge in addition to the delayed output.
