14.4.2.11 Port x PHY Interrupt Source Flags Register (PHY_INTERRUPT_SOURCE_x)
Index (decimal): 29
Size:
16 bits
This read-only register is used to determine to source of various Port x PHY interrupts. All interrupt
source bits in this register are read-only and latch high upon detection of the corresponding interrupt
(if enabled). A read of this register clears the interrupts. These interrupts are enabled or masked via
the Port x PHY Interrupt Mask Register (PHY_INTERRUPT_MASK_x).

INT5
This interrupt source bit indicates a remote fault has been detected.
0: Not source of interrupt
1: Remote fault detected
INT4
This interrupt source bit indicates a Link Down (link status negated).
0: Not source of interrupt
1: Link Down (link status negated)
INT3
This interrupt source bit indicates an Auto-Negotiation LP acknowledge.
0: Not source of interrupt
1: Auto-Negotiation LP acknowledge
INT2
This interrupt source bit indicates a Parallel Detection fault.
0: Not source of interrupt
1: Parallel Detection fault
INT1
This interrupt source bit indicates an Auto-Negotiation page received.
0: Not source of interrupt
1: Auto-Negotiation page received
