Timer Counter
The Timer/Counter (TC) includes three identical 16-bit Timer/Counter channels.
Each channel can be independently programmed to perform a wide range of functions includ-
ing frequency measurement, event counting, interval measurement, pulse generation, delay
timing and pulse width modulation.
Each channel has three external clock inputs, five internal clock inputs and two multi-purpose
input/output signals which can be configured by the user. Each channel drives an internal
interrupt signal which can be programmed to generate processor interrupts.
The Timer/Counter block has two global registers which act upon all three TC channels.
The Block Control Register allows the three channels to be started simultaneously with the
same instruction.
The Block Mode Register defines the external clock inputs for each channel, allowing them to
be chained.
