2.3.4 32-kHz crystal oscillator
The JN5169 device has an internal 32-kHz RC oscillator. In order to provide more
accurate system timings, an external 32-kHz crystal can be used with the device. This is
provided on the JN5169 USB dongle and can be enabled from the JN5169 application
using the JN5169 Integrated Peripherals API - refer to the JN5169 Integrated Peripherals
API User Guide (JN-UG-3087).
