CX Mask — R/W.
0 = Interrupt not masked.
1 = Disable the generation of a CX interrupt.
FR Mask — R/W.
0 = Interrupt not masked.
1 = Disable the generation of an FR interrupt.
CNA Mask — R/W.
0 = Interrupt not masked.
1 = Disable the generation of a CNA interrupt.
RNR Mask — R/W.
0 = Interrupt not masked.
1 = Disable the generation of an RNR interrupt.
ER Mask — R/W.
0 = Interrupt not masked.
1 = Disable the generation of an ER interrupt.
FCP Mask — R/W.
0 = Interrupt not masked.
1 = Disable the generation of an FCP interrupt.
Software Generated Interrupt (SI) — WO.
0 = No Effect.
1 = Setting this bit causes the LAN Controller to generate an interrupt.
Interrupt Mask (IM) — R/W. This bit enables or disables the LAN Controller’s assertion of the
INTA# signal. This bit has higher precedence that the Specific Interrupt Mask bits and the SI bit.
0 = Enable the assertion of INTA#.
1 = Disable the assertion of INTA#.
