Software Interrupt (SW_INT). This interrupt is generated when the
SW_INT_EN bit is set high. Writing a one clears this interrupt.
Reserved
TX Stopped (TXSTOP_INT). This interrupt is issued when STOP_TX bit
in TX_CFG is set, and the transmitter is halted.
RX Stopped (RXSTOP_INT).
halted.
RX Dropped Frame Counter Halfway (RXDFH_INT). This interrupt is
issued when the RX Dropped Frames Counter counts past its halfway
point (7FFFFFFFh to 80000000h).
Reserved
TX IOC Interrupt (TX_IOC). When a buffer with the IOC flag set has
finished being loaded into the TX FIFO, this interrupt is generated.
RX DMA Interrupt (RXD_INT). This interrupt is issued when the amount
of data programmed in the RX DMA Count (RX_DMA_CNT) field of the
RX_CFG register has been transferred out of the RX FIFO.
GP Timer (GPT_INT). This interrupt is issued when the General Purpose
timer wraps past zero to FFFFh.
PHY (PHY_INT). Indicates a PHY Interrupt event.
Power Management Event Interrupt (PME_INT). This interrupt is issued
when a Power Management Event is detected as configured in the
PMT_CTRL register. This interrupt functions independent of the PME
signal, and will still function if the PME signal is disabled. Writing a '1'
clears this bit regardless of the state of the PME hardware signal.

description of the conditions that will cause an RXE.
INT_STS—Interrupt Status Register
This register contains the current status of the generated interrupts. Writing a 1 to the corresponding
bits acknowledges and clears the interrupt.
Detection of a Power Management Event, and assertion of the PME
signal will not wakeup the LAN89218. The LAN89218 will only wake up
when it detects a host write cycle of any data to the BYTE_TEST
register.
The Interrupt Deassertion interval does not apply to the PME interrupt.
