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 15-0
IOCFx<15:0>: Interrupt-on-Change Flag x bits
1 = An enabled change was detected on the associated pin; set when IOCPx = 1 and a positive edge was
detected on the IOCx pin, or when IOCNx = 1 and a negative edge was detected on the IOCx pin
0 = No change was detected or the user cleared the detected change
Note 1:
It is not possible to set the IOCFx register bits with software writes (as this would require the addition of
significant logic). To test IOC interrupts, it is recommended to enable the IOC functionality on one or more
GPIO pins and then use the corresponding LATx register bit(s) to trigger an IOC interrupt.

See Table 11-3, Table 11-4 and Table 11-5 for individual bit availability in this register.
