Waveform Generator uses the match signal to generate an output according to operating mode
set by the WGM01:0 bits and Compare Output mode (COM0A1:0) bits. The max and bottom sig-
nals are used by the Waveform Generator for handling the special cases of the extreme values
in some modes of operation
(See “Modes of Operation” on page
97.).
Figure 14-3
shows a block diagram of the Output Compare unit.
