Timer 2 Compare Modes
The compare function of a timer/register combination operates as follows: the 16-bit
value stored in a compare or compare/capture register is compared with the contents of
the timer register; if the count value in the timer register matches the stored value, an
appropriate output signal is generated at a corresponding port pin and an interrupt can
be generated.
Compare Mode 0
In compare mode 0, upon matching the timer and compare register contents, the output
signal changes from low to high. lt goes back to a low level on timer overflow. As long as
compare mode 0 is enabled, the appropriate output pin is controlled by the timer circuit
only and writing to the port will have no effect. Figure 13 shows a functional diagram of
a port circuit when used in compare mode 0. The port latch is directly controlled by the
timer overflow and compare match signals. The input line from the internal bus and the
write-to-latch line of the port latch are disconnected when compare mode 0 is enabled.
