Registers Descriptions<br />
The register descriptions are presented here in ascending order of Register Address. Some registers carry<br />
several individual data fields of various sizes; from single-bit values (e.g. flags), upwards. Some data fields are<br />
spread across multiple registers. Unused bits are ‘don't care’ and writing either 0 or 1 will not affect any function<br />
of the device. After power on reset the registers will have the values indicated in the tables “Reset” column.<br />
RC Register<br />
Bit Name Mode Reset Description<br />
7:1 - r 000000 unused<br />
0 RC_EN rw 1 Enables RC oscillator. Set 0 for low power mode.<br />
