bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared HS - Bit is set in hardware
bit 7-4 IOCBF<7:4>: Interrupt-on-Change PORTB Flag bits
1 = An enabled change was detected on the associated pin.
Set when IOCBPx = 1 and a rising edge was detected on RAx, or when IOCANx = 1 and a falling edge
was detected on RBx.
0 = No change was detected, or the user cleared the detected change.
bit 3-0 Unimplemented: Read as ‘0’
