Description

MAC Address 2 high register

Fields

ADDRHI

MAC Address1 [47:32] This field contains the upper 16 bits[47:32] of the second 6-byte MAC address.

MBC

Mask Byte Control These bits are mask control bits for comparing each of the MAC Address bytes. When set high, the MAC does not compare the corresponding byte of received DA or SA with the contents of MAC Address1 registers. Each bit controls the masking of the bytes as follows: Bit 29: ETH_MACAxHR[15:8] Bit 28: ETH_MACAxHR[7:0] Bit 27: ETH_MACAxLR[31:24] Bit 26: ETH_MACAxLR[23:16] Bit 25: ETH_MACAxLR[15:8] Bit 24: ETH_MACAxLR[7:0] You can filter a group of addresses (known as group address filtering) by masking one or more bytes of the address.

SA

Source Address When this bit is set, the MAC Addressx[47:0] is used to compare with the SA fields of the received packet. When this bit is reset, the MAC Address x[47:0] is used to compare with the DA fields of the received packet.

0 (B_0x0): DA

1 (B_0x1): SA

AE

Address Enable When this bit is set, the address filter module uses the second MAC address for perfect filtering. When this bit is reset, the address filter module ignores the address for filtering.
