FUNCTIONAL DESCRIPTION Continued

CONTROL REGISTER (0000)

Bit Mnemonic Description

15 DONE

1: Enables an interrupt when both the DA and SA CAM lookups are complete.

14 P/R

1: Passes all frames, 0: Rejects all frames. NETEN must be set to 0 for this option.

13 NETEN

1: Enables network filtering, 0: Disables network filtering.

12 ERR

1: Enables an interrupt for a frame error caused by loss of carrier or collision.

11 FULL

1: Enables an interrupt if the LANCAM is full.

10 NODA

1: Enables an interrupt for a no-match on DA.

9 NOSA

1: Enables an interrupt for a no-match on SA.

8 DA

1: Enables an interrupt for a DA match.

7 SA

1: Enables an interrupt for an SA match.

6 REJECT

1: Enables an interrupt for a reject.

5 DAPON

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.

4 SAPON

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.

3 DAEN

1: Enables asserting the /REJECT pin after a DA compares, based on bit 5.

2 SAEN

1: Enables asserting the /REJECT pin after an SA compares, based on bit 4.

1 LEARN

1: Enables auto-learning on no-match of SA.

0 ASSOC

1: Enables a read of Associated data after a DA match.
