NOTES:
1. All signals are shown relative to the rising edge of BYTCLK.
2. Only the timing of the DA match indication is given. The SA match indication would need to be provided to the MAC
six bytes later with the same relative timing for the proper SA actions to occur.
3.
ADDR16 only changes, if necessary, with the BYTCLK cycle on the receipt of the second byte of the DA and
remains level until a different address size is detected on a following address cycle; thus, two timing values are
given, 34 and 35, for the possible transitions.
4. Figure 11-4 shows timing requirements for the CAM interface signal timing. This figure is drawn based on the
functional timing required when EXT_DA_MATCH = 0. For other functional timing, see Section 9.
