89 / 173 page  STM32F21xxx Electrical characteristics Doc ID 17050 Rev 8 89/173 Figure 33 and Figure 34 show the main PLL output clock waveforms in center spread and down spread modes, where: F0 is fPLL_OUT nominal. Tmode is the modulation period. md is the modulation depth. Figure 33. PLL output clock waveforms in center spread mode Figure 34. PLL output clock waveforms in down spread mode 5.3.12 Memory characteristics Flash memory The characteristics are given at TA = –40 to 105 °C unless otherwise specified.
