Chapter 11 Ethernet Media Access Controller (EMACV1)
Write: Anytime, but the user must not change this field while TXACT is set.
The transmit end-of-frame pointer (TXEFP) 11-bit field specifies the address offset of the last frame byte
that was stored in the transmit buffer. The base address of the transmit buffer is determined by BUFMAP.
11.3.2.19 Multicast Hash Table (MCHASH)
The multicast hash table (MCHASH) contains the 64-bit hash table used in the address recognition process
for receive frames with a multicast address.
configure this register.
Read: Anytime.
Write: Anytime, but the user must not change this field while EMACE is set.

11.3.2.20 MAC Unicast Address (MACAD)
The MAC unicast address (MACAD) registers contain the 48-bit address used for identifying an exact
match in the address recognition process by comparing the 48-bit address with the destination address field
of unicast receive frames. In addition, the 48-bit address is used in the 6-byte source address field while
transmitting PAUSE frames.
These registers are write-once after reset. The Ethernet MAC address must be a unique number for each
device. Ethernet MAC addresses are assigned by the IEEE Standards Association (IEEE-SA). This address
