Figure 33. Effects of Unsynchronized OCR Latching in Up/Down Mode
Figure 34. Effects of Unsynchronized OCR Latching in Overflow Mode.
Note:
During the time between the write and the latch operation, a read from the Output Com-
pare Registers will read the contents of the temporary location. This means that the
most recently written value always will read out of OCR0 and OCR2.
When the Output Compare Register contains $00 or $FF, and the up/down PWM mode
is selected, the output PB0(OC0/PWM0)/PB1(OC2/PWM2) is updated to low or high on
the next compare match according to the settings of COMn1/COMn0. This is shown in
Table 13. In overflow PWM mode, the output PB0(OC0/PWM0)/PB1(OC2/PWM2) is
held low or high only when the Output Compare Register contains $FF.
