10.11 Timer Counter
Three 16-bit Timer Counter Channels
– Two output compare or one input capture per channel
Wide range of functions including:
– Frequency measurement
– Event counting
– Interval measurement
– Pulse generation
– Delay timing
– Pulse Width Modulation
– Up/down capabilities
Each channel is user-configurable and contains:
– Three external clock inputs
Five internal clock inputs, as defined in Table 10-4
– Two multi-purpose input/output signals
– Two global registers that act on all three TC channels
10.12 Pulse Width Modulation Controller
Four channels, one 16-bit counter per channel
Common clock generator, providing thirteen different clocks
– One Modulo n counter providing eleven clocks
– Two independent linear dividers working on modulo n counter outputs
Independent channel programming
– Independent enable/disable commands
– Independent clock selection
– Independent period and duty cycle, with double buffering
– Programmable selection of the output waveform polarity
– Programmable center or left aligned output waveform
