17.4.2
When an event occurs that sets a bit in EIR, an interrupt occurs if the corresponding bit in the interrupt
mask register (EIMR) is also set. Writing a 1 to an EIR bit clears it; writing 0 has no effect. This register
is cleared upon hardware reset.
These interrupts can be divided into operational interrupts, transceiver/network error interrupts, and
internal error interrupts. Interrupts which may occur in normal operation are GRA, TXF, TXB, RXF, RXB,
and MII. Interrupts resulting from errors/problems detected in the network or transceiver are HBERR,
BABR, BABT, LC, and RL. Interrupts resulting from internal errors are HBERR and UN.
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
via the MIB counters.
