18.3.6
MAHR is a 32 -bit readable/writable register that specifies the upper 32 bits of the 48-bit MAC
address. The settings in this register are normally made in the initialization process after a reset.
The MAC address setting must not be changed while the transmitting and receiving functions are
enabled. To switch the MAC address setting, return the EtherC and E-DMAC to their initial states
by means of the SWR bit in EDMR before making settings again.
18.3.7
MALR is a 32-bit readable/writable register that specifies the lower 16 bits of the 48-bit MAC
address. The settings in this register are normally made in the initialization process after a reset.
The MAC address setting must not be changed while the transmitting and receiving functions are
enabled. To switch the MAC address setting, return the EtherC and E-DMAC to their initial states
by means of the SWR bit in EDMR before making settings again.

Description
MAC Address Bits
These bits are used to set the upper 32 bits of the
MAC address.
If the MAC address is 01-23-45-67-89-AB
(hexadecimal), the value set in this register is
H'01234567.
Description
Reserved
These bits are always read as 0. The write value
should always be 0.
MAC Address Bits 15 to 0
These bits are used to set the lower 16 bits of the MAC
address.
If the MAC address is 01-23-45-67-89-AB
(hexadecimal), the value set in this register is
H'000089AB.
