The following table shows the register bit fields.
MAC Multicast Table 1 Register (MTR1 Offset 0x0024)
The 64 bit multicast table is used for group address filtering. The hash value is defined as the six most significant bits of
the CRC of the DA. The two most significant bits select the register to be used, while the other determines the bit within
the register.
The following table shows the register bit fields.
Interrupt Enable Register (INTEN Offset 0x0028)
This register enables the interrupts from the internal or external sources.
The following table shows the register bit fields.

Description
MTR0 Multicast Table 0
When appropriate bit is set, the packet received with DA matches the
CRC hashing function is received without being filtered.
Note: when the receive all (RXRA) or receive multicast (RXRM) bit is set
in the RXCR then all multicast addresses are received regardless of the
multicast table value..
