131 / 386 page  131 2467S–AVR–07/09 ATmega128 The extreme values for the OCRnx Register represent special cases when generating a PWM waveform output in the phase correct PWM mode. If the OCRnx is set equal to BOTTOM the output will be continuously low and if set equal to TOP the output will be set to high for non- inverted PWM mode. For inverted PWM the output will have the opposite logic values. If OCRnA is used to define the TOP value (WGMn3:0 = 9) and COMnA1:0 = 1, the OCnA Output will toggle with a 50% duty cycle. Timer/Counter Timing Diagrams The Timer/Counter is a synchronous design and the timer clock (clk Tn) is therefore shown as a clock enable signal in the following figures. The figures include information on when interrupt flags are set, and when the OCRnx Register is updated with the OCRnx buffer value (only for modes utilizing double buffering). Figure 55 shows a timing diagram for the setting of OCFnx. Figure 55. Timer/Counter Timing Diagram, Setting of OCFnx, no Prescaling Figure 56 shows the same timing data, but with the prescaler enabled. Figure 56. Timer/Counter Timing Diagram, Setting of OCFnx, with Prescaler (f clk_I/O/8) clk Tn (clk I/O/1) OCFnx clk I/O OCRnx TCNTn OCRnx Value OCRnx - 1 OCRnx OCRnx + 1 OCRnx + 2 OCFnx OCRnx TCNTn OCRnx Value OCRnx - 1 OCRnx OCRnx + 1 OCRnx + 2 clk I/O clk Tn (clk I/O/8) |
