3.5.3
Analog Circuits
The CRG has three analog circuits (RCOSC block, XOSC block, and SYSPLL block). The following shows the
setting confirmation registers of each analog circuit. Some of them are RW registers, but use them as RO registers.
For descriptions of the RF block, refer to Section 3.12.
3.5.3.1 RCOSC Block Setting Confirmation
The RCOSC is an internal ring oscillator that operates at 8.192 MHz. In initial state, the oscillation frequency is
higher than 8.192 MHz, but by using the calibration process of the API, it can be adjusted to 8.192 MHz.
