Reserved, should be cleared.
Interrupt vector. IVEC gives the highest outstanding priority FEC interrupt. The bit field meanings (from
low priority to high priority) are as follows:
00 No pending FEC interrupt
01 Non-time critical interrupt (All interrupts except TXB, TXF, RXB, and RXF.)
10 Transmit interrupt
11 Receive interrupt
Reserved, should be cleared.
