Figure 4-33. Effects on Unsynchronized OCR1 Latching
Note:
Figure 4-34. Effects of Unsynchronized OCR1 Latching in Overflow Mode
Note:
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
the output OC1A/OC1B is held Low or High only when the Output Compare Register contains
TOP.
