Section 10 16-Bit Timer Pulse Unit (TPU)
PWM Mode
In this mode, a PWM waveform is output. The output level can be set by means of TIOR. A PWM
waveform with a duty of between 0% and 100% can be output, according to the setting of each
TGR register.
Phase Counting Mode
In this mode, TCNT is incremented or decremented by detecting the phases of two clocks input
from the external clock input pins in channels 1, 2, 4, and 5. When phase counting mode is set, the
corresponding TCLK pin functions as the clock pin, and TCNT performs up- or down-counting.
This can be used for two-phase encoder pulse input.
10.4.2
Basic Functions
Counter Operation
When one of bits CST0 to CST5 is set to 1 in TSTR, the TCNT counter for the corresponding
channel starts counting. TCNT can operate as a free-running counter, periodic counter, and so on.
