Figure 39. PWM polarity inversion
The data flip flop (DFF) applies the polarity inversion when triggered by the counter overflow
input.
●
Figure 40. PWM function
The maximum value of ATR is 4094 because it must be lower than the DCR value
which must be 4095 in this case.
Polarity inversion
The polarity bits can be used to invert any of the four output signals. The inversion is
synchronized with the counter overflow if the corresponding transfer bit in the ATCSR2
register is set (reset value). See
Output control
The PWMx output signals can be enabled or disabled using the OEx bits in the
PWMCR register.
