WDT
11. DFLL clock is unstable with a fast reference clock
12. DFLLIF indicates coarse lock too early
13. DFLLIF dithering does not work
14. SCIF VERSION register reads 0x100
15. DFLLVERSION register reads 0x200
16. RCCRVERSION register reads 0x100
17. OSC32VERSION register reads 0x100
18. VREGVERSION register reads 0x100
19. RC120MVERSION register reads 0x100
1. Clearing of the WDT in window mode
Disable generic clocks before going to sleep modes where clock sources are stopped to
save power.
The DFLL clock can be unstable when a fast clock is used as reference clock in closed loop
mode.
Fix/Workaround
Use the 32 KHz crystal oscillator clock or a clock with similar frequency as DFLLIF reference
clock.
The DFLLIF might indicate coarse lock too early, the DFLL will lose coarse lock and regain it
later.
Fix/Workaround
Use max step size (DFLL0MAXSTEP.MAXSTEP) of 4 or higher.
The DFLLIF dithering does not work.
Fix/Workaround
None.
The VERSION register reads 0x100 instead of 0x102.
Fix/Workaround
None.
The DFLLVERSION register reads 0x200 instead of 0x201.
Fix/Workaround
None.
The RCCRVERSION register reads 0x100 instead of 0x101.
Fix/Workaround
None.
The OSC32VERSION register reads 0x100 instead of 0x101.
Fix/Workaround
None.
The VREGVERSION register reads 0x100 instead of 0x101.
Fix/Workaround
None.
The RC120MVERSION register reads 0x100 instead of 0x101.
