6.4.2. 10kHz Oscillator
The AMIS-53000 has an internal 10kHz oscillator. This oscillator is running whenever the AMIS-53000 is in standby or idle modes.
This very low power oscillator provides the clock for timing functions such as Sniff receive, Burst transmit or housekeeping. The
oscillator is trimmed in the calibration instructions.
Setup registers descriptions:
10k Oscillator Trim- The value of the calibration for the 10kHz oscillator. (See Section 6.10.1.4)**
6.4.3. System Clock
The AMIS-53000 provides a divided version of the external reference oscillator (typically 24MHz) as an output to an external
host/controller or other circuits needing a clock.
