The active time of PSCOUTn0 is given by the OT0 value. The active time of PSCOUTn1 is given by the OT1 value. Both of them are 12 bit values. Thanks to DT0 & DT1 to adjust the dead time between PSCOUTn0 and PSCOUTn1 active signals. The waveform frequency is defined by the following equation: 16.7.2.2 Enhanced Mode The Enhanced Mode uses the previously described method to generate a high resolution frequency. Figure 16-13. Enhanced Mode, Timing Diagram The supplementary step in counting to generate fb2 is added on the PSCn0 signal while needed in the frame according to the fractional divider. See Table 16-5, “Distribution of fb2 in the modu- lated frame,” on page 143 . The waveform frequency is defined by the following equations: d is the fractional divider factor. f PSCn 1 PSCnCycle ------------------------------ = f CLK_PSCn OT0 OT1 DT0 DT1 +++ ---------------------------------------------------------------------- = PSCOUTn0 T1 Period PSCOUTn1 OT0 OT1 DT1 DT0 T2 OT0 OT1+1 DT1 DT0 DT0 f1 PSCn 1 T 1 ------ fCLK_PSCn OT0 OT1 DT0 DT1 ++ + ---------------------------------------------------------------------- == f2 PSCn 1 T2 ------ f CLK_PSCn OT0 OT1 DT0 DT11 ++ ++ -------------------------------------------------------------------------------- == f AVERAGE 16 d – 16 ---------------f1 PSCn d 16 ------f2 PSCn + = |
