Definitions
The following definitions are used extensively throughout the Timer/Counter documentation:
Table 14-1.
In general the term Timer is used when the Timer/Counter clock control is handled by an internal
source and the term Counter is used if the clock is given externally (from an event).

Timer/Counter definitions
Description
The Counter reaches the BOTTOM when it becomes zero.
The Counter reaches MAXimum when it becomes all ones.
The Counter reaches the TOP when it becomes equal to the highest value in the
count sequence. The TOP value can be equal to the period (PER) or the Compare
Channel A (CCA) register setting. This is selected by the Waveform Generator Mode.
The Timer/Counter signalizes an update when it reaches BOTTOM or TOP
dependent of the Waveform Generator Mode.
