Hello Support,

CCUCON3 Bit 4 as well as CCUCON4 Bit24, both says Back-Up Clock Monitoring Enable for Aurix 2G.
There is only one set of Threshold values in CCUCON4 Register with respect to 100MHz Backup Clock and PLL0 ratio.
So, what is the functional difference between these two bits in Aurix 2G?
Best Regards

See Figure 90 Clock Monitor:
- CCUCON3.BACKMONEN is a test of whether fBACK is running at all.
- CCUCON4.MONEN tests fBACK against a configurable upper and lower limit.
