33. Timer Counter (TC)
33.1 Overview
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 including 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.
Table 33-1 gives the assignment of the device Timer Counter clock inputs common to Timer Counter 0 to 2
