Notes: 1. These options should only be used when not operating close to the maximum frequency of the device, and

only if frequency stability at start-up is not important for the application. These options are not suitable for

crystals.

2. These options are intended for use with ceramic resonators and will ensure frequency stability at start-up.

They can also be used with crystals when not operating close to the maximum frequency of the device, and if

frequency stability at start-up is not important for the application.
