Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
PLL Lock Interrupt Mask
This bit specifies whether a PLL Lock interrupt is promoted to a controller
interrupt. If set, an interrupt is generated if PLLLRIS in RIS is set;
otherwise, an interrupt is not generated.
Current Limit Interrupt Mask
This bit specifies whether a current limit detection is promoted to a
controller interrupt. If set, an interrupt is generated if CLRIS is set;
otherwise, an interrupt is not generated.
Internal Oscillator Fault Interrupt Mask
This bit specifies whether an internal oscillator fault detection is promoted
to a controller interrupt. If set, an interrupt is generated if IOFRIS is set;
otherwise, an interrupt is not generated.
Main Oscillator Fault Interrupt Mask
This bit specifies whether a main oscillator fault detection is promoted
to a controller interrupt. If set, an interrupt is generated if MOFRIS is set;
otherwise, an interrupt is not generated.
LDO Power Unregulated Interrupt Mask
This bit specifies whether an LDO unregulated power situation is
promoted to a controller interrupt. If set, an interrupt is generated if
LDORIS is set; otherwise, an interrupt is not generated.
Brown-Out Reset Interrupt Mask
This bit specifies whether a brown-out condition is promoted to a
controller interrupt. If set, an interrupt is generated if BORRIS is set;
otherwise, an interrupt is not generated.
PLL Fault Interrupt Mask
This bit specifies whether a PLL fault detection is promoted to a controller
interrupt. If set, an interrupt is generated if PLLFRIS is set; otherwise,
an interrupt is not generated.
