Prior to entering Idle Mode, software must clear both FMODE and FSEL (the timer must be disabled in order to clear
either bit) keeping the PLLEN bit 1.
Using a separate instruction (e.g. RBIT PLLEN, PSCALE) disable the PLL by clearing the PLLEN bit.
Software may then instruct the device to enter Idle Mode.
If all disabled circuits must be re-enabled after exiting from Idle Mode, repeat all initial steps enabling all circuits in the
appropriate order as well as waiting T
