+
+  Now even you use all these new 16 ISR-based timers,with their maximum interval practically unlimited (limited only by
+  unsigned long miliseconds), you just consume only one Portenta_H7 STM32 timer and avoid conflicting with other cores' tasks.
+  The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
+  Therefore, their executions are not blocked by bad-behaving functions / tasks.
+  This important feature is absolutely necessary for mission-critical tasks.
