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.
Mask PHY Interrupt
This bit masks the PHYINT bit in the MACRIS register from being
asserted.
Mask MII Transaction Complete
This bit masks the MDINT bit in the MACRIS register from being
asserted.
Mask Receive Error
This bit masks the RXER bit in the MACRIS register from being asserted.
Mask FIFO Overrrun
This bit masks the FOV bit in the MACRIS register from being asserted.
Mask Transmit FIFO Empty
This bit masks the TXEMP bit in the MACRIS register from being
asserted.
Mask Transmit Error
This bit masks the TXER bit in the MACRIS register from being asserted.
Mask Packet Received
This bit masks the RXINT bit in the MACRIS register from being
asserted.
