Description
MOSC Power Up Masked Interrupt Status
Value Description
0 When read, a 0 indicates that sufficient time has not passed for
the MOSC PLL to lock.
A write of 0 has no effect on the state of this bit.
1 When read, a 1 indicates that an unmasked interrupt was
signaled because sufficient time has passed for the MOSC PLL
to lock.
Writing a 1 to this bit clears it and also the MOSCPUPRIS bit in
the RIS register.
USBPLLLMIS
RW1C
0
USB PLL Lock Masked Interrupt Status
Value Description
0 When read, a 0 indicates that sufficient time has not passed for
the USB PLL to lock.
A write of 0 has no effect on the state of this bit.
1 When read, a 1 indicates that an unmasked interrupt was
signaled because sufficient time has passed for the USB PLL
to lock.
Writing a 1 to this bit clears it and also the USBPLLLRIS bit in
the RIS register.
PLLLMIS
RW1C
0
PLL Lock Masked Interrupt Status
Value Description
0 When read, a 0 indicates that sufficient time has not passed for
the PLL to lock.
A write of 0 has no effect on the state of this bit.
1 When read, a 1 indicates that an unmasked interrupt was
signaled because sufficient time has passed for the PLL to lock.
Writing a 1 to this bit clears it and also the PLLLRIS bit in the
RIS register.

0x0
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.
RO
0
Main Oscillator Failure Masked Interrupt Status
Value Description
0 When read, a 0 indicates that the main oscillator has not failed.
A write of 0 has no effect on the state of this bit.
1 When read, a 1 indicates that an unmasked interrupt was
signaled because the main oscillator failed.
Writing a 1 to this bit clears it and also the MOFRIS bit in the
RIS register.
