Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Clear PHY Interrupt
A write of a 1 clears the PHYINT interrupt read from the MACRIS
register.
Clear MII Transaction Complete
A write of a 1 clears the MDINT interrupt read from the MACRIS register.
Clear Receive Error
A write of a 1 clears the RXER interrupt read from the MACRIS register.
Clear FIFO Overrun
A write of a 1 clears the FOV interrupt read from the MACRIS register.
Clear Transmit FIFO Empty
A write of a 1 clears the TXEMP interrupt read from the MACRIS register.
Clear Transmit Error
A write of a 1 clears the TXER interrupt read from the MACRIS register
and resets the TX FIFO write pointer.
Clear Packet Received
A write of a 1 clears the RXINT interrupt read from the MACRIS register.
