Interrupt Detect Register
The MVME3100 provides an Interrupt Detect register that may be read by the system software to
determine which of the Ethernet PHYs originated their combined (OR’d) interrupt.
TSEC1_PHY
TSEC1 PHY interrupt. If cleared, the TSEC1 interrupt is not asserted. If set, the TSEC1 interrupt is
asserted.
TSEC2_PHY
TSEC2 PHY interrupt. If cleared, the TSEC2 interrupt is not asserted. If set, the TSEC2 interrupt is
asserted.
FEC_PHY
FEC PHY interrupt. If cleared, the FEC interrupt is not asserted. If set, the FEC interrupt is asserted.
RSVD
Reserved for future implementation.
