When address fields are mismatch with set value, following procedure is determined by the setting to ADDFIL_NG_SET

([PACKET_MODE_SET:B0 0x45(5)]) and packet discard completion interrupt (INT[03] group1) timing is defined by

ADDFIL_IDLE_DET ([PACKET_MODE_SET:B0 0x45(0)]).

ADDFIL_NG_SET (bit5)

0b1: When address-mismatch is detected, discarding RX data after RX completetion.

0b0: When address-mismatch is detected, discarding RX data immediately.

ADDFIL_IDLE_DET (bit0)

0b1: After discarding RX data perform CCA and “IDLE” is detected, INT[03] will be generated.

0b0: After discarding RX data, INT[03] will be generated immediately.

When RX data is discarded, adding to INT[03] generation, discarded packet can be counted up to 1023 and result stored in

[DISCARD_COUNT0:B2 0x6F] and [DISCARD_COUNT1:B2 0x70] registers.

[Note]

When using Address Filtering function while FEC function is enabled, if INT[03] is notified. PHY reset by [RST_SET:B0

0x01] should be required. If not issuing PHY reset, after that, ML7396 can not receive packet with address match also.
