The crystal oscillator must be in power down for a
guard time before it is used again. This
Power-down guard time
requirement is valid for all modes of operation. The
3
ms
need for power-down guard time can vary with
crystal type and load.

(1) The calibrated 32-kHz RC oscillator frequency is the 32-MHz XTAL frequency divided by 977.
(2) Frequency drift when temperature changes after calibration
(3) Frequency drift when supply voltage changes after calibration
(4) When the 32-kHz RC oscillator is enabled, it is calibrated when a switch from the 16-MHz RC oscillator to the 32-MHz crystal oscillator
is performed while SLEEPCMD.OSC32K_CALDIS is 0.
