Description
IDR0
ID Register 0.
ID registers 0-5 are only permitted to read/write via 4-byte access.
Read access can be byte, word, or double word access. The initial
value is autoloaded from the EEPROM EthernetID field.
IDR1
ID Register 1.
IDR2
ID Register 2.
IDR3
ID Register 3.
IDR4
ID Register 4.
IDR5
ID Register 5.
-
Reserved.
MAR0
Multicast Address Register 0.
The MAR register 0-7 are only permitted to read/write via 4-byte
access. Read access can be byte, word, or double word access. The
driver is responsible for initializing these registers.
MAR1
Multicast Address Register 1.
MAR2
Multicast Address Register 2.
MAR3
Multicast Address Register 3.
MAR4
Multicast Address Register 4.
MAR5
Multicast Address Register 5.
MAR6
Multicast Address Register 6.
MAR7
Multicast Address Register 7.
