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

need for power-down guard time can vary with

crystal type and load.

Calibration time(4)

(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.
