31 TEMPHIGH
Set when the value of a periodic temperature measurement is higher or equal than TEMPHIGH in EMU_TEMPLIMITS
30 TEMPLOW
Set when the value of a periodic temperature measurement is lower or equal than TEMPHIGH in EMU_TEMPLIMITS
29 TEMP
Set when a new periodic temperature measurement is available
28:26 Reserved
25 VSCALEDONE
Will be set when all the steps needed for voltage scaling is done. For voltage upgrade, the software can start increasing
clock frequency after this interrupt. For voltage downgrade, this will indicate that hardware has finished all the steps includ-
ing updating of BOD levels and regultor controls, but voltage drop may take lot longer due to load current
24 EM23WAKEUP
Will be set when the system wakes up from EM2 and EM3. This interrupt can be used to run initialization code need to
reconfigure the system when returning from EM2 and EM3.
23:21 Reserved
20 DCDCINBYPASS
DCDC is in bypass
19 DCDCLNRUNNING
This flag is set once the DCDC regulator has started to run in LN mode
18 DCDCLPRUNNING
This flag is set once the DCDC regulator has started to run in LP mode
