6.1.10 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.

OPER R
RESET 1
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.

6.1.11 Presence Detect Register

The MVME3100 provides a Presence Detect register that may be read by the system software
to determine the presence of optional devices.
