Preliminary
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 Raw Interrupt Status
This bit is set when the PLL T
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 is currently active. This is an unregistered signal
from the brown-out detection circuit. 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).
