Ethernet Controller
Register 25: Ethernet PHY Management Register 17 – Interrupt Control/Status
(MR17), address 0x11
This register provides the means for controlling and observing the events, which trigger a PHY
interrupt in the MACRIS register. This register can also be used in a polling mode via the MII Serial
Interface as a means to observe key events within the PHY via one register address. Bits 0 through
7 are status bits, which are each set to logic 1 based on an event. These bits are cleared after the
register is read. Bits 8 through 15 of this register, when set to logic 1, enable their corresponding
bit in the lower byte to signal a PHY interrupt in the MACRIS register.

Description
Jabber Interrupt Enable
When set, enables system interrupts when a Jabber condition is detected
by the PHY.
Receive Error Interrupt Enable
When set, enables system interrupts when a receive error is detected
by the PHY.
Page Received Interrupt Enable
When set, enables system interrupts when a new page is received by
the PHY.
Parallel Detection Fault Interrupt Enable
When set, enables system interrupts when a Parallel Detection Fault is
detected by the PHY.
LP Acknowledge Interrupt Enable
When set, enables system interrupts when FLP bursts are received with
the Acknowledge bit during Auto-Negotiation.
Link Status Change Interrupt Enable
When set, enables system interrupts when the Link Status changes
from OK to FAIL.
Remote Fault Interrupt Enable
When set, enables system interrupts when a Remote Fault condition is
signaled by the link partner.
Auto-Negotiation Complete Interrupt Enable
When set, enables system interrupts when the Auto-Negotiation
sequence has completed successfully.
