This bit is valid only when the selected clock source for REFA passes the internal Frequency Synthesizer
In normal operation:
0: Output the clock which is locked to the selected clock source and the frequency is programmed in the FREQ[2:0] bits (b2~0,
REFCF). (default)
1: Output free running clock which is locked to MCLK and the frequency is programmed in the FREQ[2:0] bits (b2~0, REFCF).
When the selected clock source is lost, this bit, together with the FS_BYPAS bit (b4, REFCF) and the REFH bit (b5, REFCF),
controls the output on REFA:
2 - 0
FREQ[2:0]
These bits are valid only when the Frequency Synthesizer on REFA is enabled. These bits determine the output clock frequency.
