Figure 4-29. Effects of Unsynchronized OCR Latching in Up/Down Mode
Note:
Figure 4-30. Effects of Unsynchronized OCR Latching in Overflow Mode.
Note:
During the time between the write and the latch operation, a read from the Output Compare
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 PE1(OC0/PWM0)/PE3(OC2/PWM2) is updated to Low or High on the next
compare match according to the settings of COMn1/COMn0. This is shown in
overflow PWM mode, the output PE1(OC0/PWM0)/PE3(OC2/PWM2) is held Low or High only
when the Output Compare Register contains $FF.
