4.10.4. XO clock

The XO clock is the high-frequency, high-precision clock source for 26MHz operation. The XO

clock is sourced from an external 26MHz crystal as shown in Figure 15. The XO is controlled by the

AON power state and is enabled by default after cold boot. This clock can be divided down to

13MHz, 2MHz and 1MHz upon the DOOPD requirements.

Clock performance reported below was measured at the following condition: Ta = 25°C, VCC=3.0V,

unless otherwise noted.
