Description
Reserved bits return an indeterminate value, and should
never be changed.
PLL Lock Raw Interrupt Status
This bit is set when the PLL T_READY Timer asserts.
Current Limit Raw Interrupt Status
This bit is set if the LDO’s CLE output asserts.
Internal Oscillator Fault Raw Interrupt Status
This bit is set if an internal oscillator fault is detected.
Main Oscillator Fault Raw Interrupt Status
This bit is set if a main oscillator fault is detected.
LDO Power Unregulated Raw Interrupt Status
This bit is set if a LDO voltage is unregulated.
Brown-Out Reset Raw Interrupt Status
This bit is the raw interrupt status for any brown-out
conditions. If set, a brown-out condition was detected. An
interrupt is reported if the BORIM bit in the IMC register is
set and the BORIOR bit in the PBORCTL register is cleared.
PLL Fault Raw Interrupt Status
This bit is set if a PLL fault is detected (stops oscillating).
