Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-0 IFS31-IFS0: Interrupt Flag Status bits
1 = Interrupt request has occurred
0 = No interrupt request has occurred
Note: This register represents a generic definition of the IFSx register. Refer to Table 7-1 for the exact bit
definitions.
