You can also cascade counter 0 and counter 1 together as one 32-bit
counter/timer, and it’s configured by control bit - CTR32Set.
2.13 LED and Buzzer for System Diagnosis
In a “headless application” (an application without a monitor display), it is
always difficult to know the system status. Another PC may be needed to
monitor a headless device's status via RS-232 or Ethernet. In order to
solve this problem, UNO-4672 offers a programmable LED indicator and
buzzer. They can be programmed to show a systems status by LED indica-
tor flickering and buzzer alarm.
