register (IMASK), the event also causes a hardware interrupt at the PIC. A bit in the interrupt event register
is cleared by writing a 1 to that bit position. A write of 0 has no effect.
Each eTSEC can issue three kinds of hardware interrupt to the PIC:
Some of the error interrupts are independently counted in the MIB block counters. Software may choose
to mask off these interrupts because these errors are visible to network management through the MIB
counters.

1. Transmit data frame interrupts—Issued whenever bits TXB or TXF of IEVENT are set to 1 and
2. Receive data frame interrupts—Issued whenever bits RXB or RXF of IEVENT are set to 1 and

either transmit interrupt coalescing is disabled or the interrupt coalescing thresholds have been met
for TXF. To negate this hardware interrupt, software must clear both TXB and TXF bits.

BABR, BABT, LC, CRL, FGPI, FIR, FIQ, DPE, PERR, EBERR, TXE, XFUN, BSY, MSRO,
MMRD, or MMRW of IEVENT are set to 1. Software must clear all of these bits to negate an
error/diagnostic/special hardware interrupt.
— Magic Packet reception event is: MAG
— Operational diagnostics are events on: GTSC, GRSC, TXC, and RXC
— Interrupts resulting from errors/problems detected in the network or transceiver are: BABR,
— Interrupts resulting from internal or combination errors are: FIR, FIQ, DPE, PERR, EBERR,
— Special function interrupts are: FGPI, MSRO, MMRD, and MMRW
