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.
MOSC Power Up Interrupt Mask
This bit specifies whether a current limit detection is promoted to a
controller interrupt. If set, an interrupt is generated if MOSCPUPRIS in
RIS is set; otherwise, an interrupt is not generated.
USB PLL Lock Interrupt Mask
This bit specifies whether a current limit detection is promoted to a
controller interrupt. If set, an interrupt is generated if USBPLLLRIS in
RIS is set; otherwise, an interrupt is not generated.
PLL Lock Interrupt Mask
This bit specifies whether a current limit detection is promoted to a
controller interrupt. If set, an interrupt is generated if PLLLRIS in RIS
is set; otherwise, an interrupt is not generated.
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.
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.
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.
