Description
1: Enables an interrupt when both the DA and SA CAM lookups are complete.
1: Passes all frames, 0: Rejects all frames. NETEN must be set to 0 for this option.
1: Enables network filtering, 0: Disables network filtering.
1: Enables an interrupt for a frame error caused by loss of carrier or collision.
1: Enables an interrupt if the LANCAM is full.
1: Enables an interrupt for a no-match on DA.
1: Enables an interrupt for a no-match on SA.
1: Enables an interrupt for a DA match.
1: Enables an interrupt for an SA match.
1: Enables an interrupt for a reject.
1: Rejects frame if there is no DA match (positive filtering).
0: Rejects frame if there is a DA match (negative filtering).
This bit is a “Don’t Care” if DAEN is 0.
1: Rejects frame if there is no SA match (positive filtering).
0: Rejects frame if there is an SA match (negative filtering).
This bit is a “Don’t Care” if SAEN is 0.
1: Enables asserting the /REJECT pin after a DA compares, based on bit 5.
1: Enables asserting the /REJECT pin after an SA compares, based on bit 4.
1: Enables auto-learning on no-match of SA.
1: Enables a read of Associated data after a DA match.
