System Control
Register 4: Raw Interrupt Status (RIS), offset 0x050
This register indicates the status for system control raw interrupts. An interrupt is sent to the interrupt
controller if the corresponding bit in the Interrupt Mask Control (IMC) register is set. Writing a 1
to the corresponding bit in the Masked Interrupt Status and Clear (MISC) register clears an interrupt
status bit.

Reset Description
0x0000.00 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.
0
VDD under BOR0 Raw Interrupt Status
Value Description
0 A VDD BOR0 condition is not currently active.
1 A VDD BOR0 condition is currently active.
Note the BOR0 bit in the PBORCTL register must be cleared to cause
an interrupt due to a BOR0 Event.
This bit is cleared by writing a 1 to the BOR0MIS bit in the MISC register.
0
VDDA Power OK Event Raw Interrupt Status
Value Description
0 VDDA power is not at its appropriate functional voltage.
1 VDDA is at an appropriate functional voltage.
This bit is cleared by writing a 1 to the VDDAMIS bit in the MISC register.
