Bank 18 Receive Byte Counter Register (0x06): RXBC
This register indicates the status of the current received frame and mirrors the Receive Byte Count word of the Receive
Frame in the RXQ.
Bank 19 Multicast Table Register 0 (0x00): MTR0
The 64-bit multicast table is used for group address filtering. This value is defined as the six most significant bits from
CRC circuit calculation result that is based on 48-bit of DA input. The two most significant bits select one of the four
registers to be used, while the others determine which bit within the register.
Multicast table register 0.
Bank 19 Multicast Table Register 1 (0x02): MTR1
Multicast table register 1.
Bank 19 Multicast Table Register 2 (0x04): MTR2
Multicast table register 2.

Receive Byte Count.
Description
MTR0 Multicast Table 0
When the appropriate bit is set, if the packet received with DA matches the CRC, the
hashing function is received without being filtered.
When the appropriate bit is cleared, the packet will drop.
Note: When the receive all (RXRA) or receive multicast (RXRM) bit is set in the RXCR,
all multicast addresses are received regardless of the multicast table value.
Description
MTR0 Multicast Table 1
When the appropriate bit is set, if the packet received with DA matches the CRC, the
hashing function is received without being filtered.
When the appropriate bit is cleared, the packet will drop.
Note: When the receive all (RXRA) or receive multicast (RXRM) bit is set in the RXCR,
all multicast addresses are received regardless of the multicast table value.
Description
MTR0 Multicast Table 2
When the appropriate bit is set, if the packet received with DA matches the CRC, the
hashing function is received without being filtered.
When the appropriate bit is cleared, the packet will drop.
Note: When the receive all (RXRA) or receive multicast (RXRM) bit is set in the RXCR,
all multicast addresses are received regardless of the multicast table value.
