3.0 Memory and I/O Mapping
There are four memory or I/O mapping used in AX88190A.
3.1 EEPROM Memory Mapping
Tab - 9 EEPROM Memory Mapping
Note : bit 3 register of LCOR in AX88190 is replaced by bit 0 of CFL in AX88190A
3.2 Attribute Memory Mapping
Tab - 10 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 AX88190A will disable MAC
transmitting and receiving operation. But the host interface will not be affected.
