3.0 Memory and I/O Mapping
There are four memories or I/O mapping used in AX88790.
3.1 EEPROM Memory Mapping
Tab – 10 EEPROM Memory Mapping
Note: bit 3 register of LCOR in AX88190 is replaced by bit 0 of CFL in AX88790
3.2 Attribute Memory Mapping
Tab – 11 Attribute Memory Mapping
Bit 0 of CFL: Enable Power Down mode
This bit is set to 1; the LAN will go into power down mode. At power down mode AX88790 will disable MAC
transmitting and receiving operation. But the host interface will not be affected.
