29 ULFRCOPHASE
Used to determine if ULFRCO is in high or low phase.
28 LFRCOPHASE
Used to determine if LFRCO is in high or low phase.
27 LFXOPHASE
Used to determine if LFXO is in high or low phase.
26 HFXOREGILOW
HFXO regulator shunt current too low. When using PEAKDETSHUNTOPTMODE=MANUAL, the REGISH value in
CMU_HFXOSTEADYSTATECTRL should be tuned up by 1 LSB.
25 HFXOAMPLOW
HFXO oscillation amplitude is too low. When using PEAKDETSHUNTOPTMODE=MANUAL, the IBTRIMXOCORE value in
CMU_HFXOSTEADYSTATECTRL should be tuned up by 1 LSB.
24 HFXOAMPHIGH
HFXO oscillation amplitude is too high. When using PEAKDETSHUNTOPTMODE=MANUAL, the IBTRIMXOCORE value in
CMU_HFXOSTEADYSTATECTRL should be tuned down by 1 LSB.
23 HFXOSHUNTOPTR-
DY
HFXO shunt current optimization is ready.
22 HFXOPEAKDETRDY 0
HFXO peak detection is ready.
21 HFXOREQ
HFXO is required by another hardware block and HFXO should typically not be disabled or deselected. Whether disabling
or deselecting of the HFXO can be performed and whether this leads to setting of HFXODISERR depends on whether the
HFXO enable/select conditions are met.
