12-bit autoreload timer 2 (AT2)
Note:
74/171
the upcounter matches the DCRx value the PWMx signals are set to a low level. To obtain a
signal on a PWMx pin, the contents of the corresponding DCRx register must be greater
than the contents of the ATR register.
The polarity bits can be used to invert any of the four output signals. The inversion is
synchronized with the counter overflow if the TRAN bit in the TRANCR register is set (reset
value). See
Figure 34. PWM inversion diagram
The maximum available resolution for the PWMx duty cycle is:
Resolution = 1 / (4096 - ATR)
To get the maximum resolution (1/4096), the ATR register must be 0. With this maximum
resolution, 0% and 100% can be obtained by changing the polarity.
