16.4.6
Each of the pins can be connected to each of the four up-counters. These counters count up when
an active edge is detected on the input pins. The counters can be written to by software to be
preloaded and the current value can be read. Two up-counters can also be configured to count both
up and down. In this case since two pins are required, the second up-counter within the pair is not
available. The pins are then referred to as up (pins 0 and 2) and down (pins 1 and 3). An active
edge on these pins will cause the counter either to count up or down, or if both edges are active
then the count will remain unchanged. In either up-counter or updown-counter mode, the counter
will generate an interrupt if an edge is detected or if the count overflows or underflows.
