Figure 38. Effects of Unsynchronized OCR1 Latching.
Figure 39. Effects of Unsynchronized OCR1 Latching in Overflow Mode
During the time between the write and the latch operation, a read from OCR1A or
OCR1B will read the contents of the temporary location. This means that the most
recently written value always will read out of OCR1A/B.
When the OCR1X contains $0000 or TOP, and the up/down PWM mode is selected, the
output OC1A/OC1B is updated to low or high on the next compare match according to
the settings of COM1A1/COM1A0 or COM1B1/COM1B0. This is shown in Table 23. In
overflow PWM mode, the output OC1A/OC1B is held low or high only when the Output
Compare Register contains TOP.
Note: x = A or B
