When the clock gear is used to reduce the system clock frequency (fsys), the prescalars within on-chip
peripherals must be programmed so that the prescaler output ( Tn) satisfies the following relationship:
Descriptions of each peripheral on the following sections include tables showing legal programming alternatives.
When the low-speed clock (fs) is used as the system clock, all on-chip peripherals except the Watchdog Timer
(WDT) and the Real-Time Counter (RTC) must be disabled.
The presclar clock source ( Tn) must not be changed while any of the peripherals to which it is supplied are
running.
