41 / 324 page  ST72561-Auto Supply, reset and clock management Doc ID 12370 Rev 8 41/324 5 Supply, reset and clock management 5.1 Introduction The device includes a range of utility features for securing the application in critical situations (for example, in case of a power brown-out), and reducing the number of external components. An overview is shown in Figure 11. For more details, refer to dedicated parametric section. 5.2 Main features ● Optional PLL for multiplying the frequency by 2 ● Reset Sequence Manager (RSM) ● Multi-Oscillator Clock Management (MO) – 4 Crystal/Ceramic resonator oscillators ● System Integrity Management (SI) – Main supply Low voltage detection (LVD) – Auxiliary Voltage detector (AVD) with interrupt capability for monitoring the main supply 5.3 Phase locked loop If the clock frequency input to the PLL is in the range 2 to 4 MHz, the PLL can be used to multiply the frequency by two to obtain an fOSC2 of 4 to 8 MHz. The PLL is enabled by option byte. If the PLL is disabled, then fOSC2 =fOSC/2. Caution: The PLL is not recommended for applications where timing accuracy is required.
