Figure 5: 16-bit mode memory mapping
The following is an example to indicate how to define a new window base address in 16-bit mode by configuring the
MEMBAS6 register. If AX88180 is allocated at the memory base address 0x20_0000 by hardware (i.e. the MEMBASE
register is allocated at 0x20_0000) and users would like to set the new window base address to 0x20_1000, the driver
should write 0x0010 to the MEMBAS6 register (offset 0x20_0006). In this case, the TX buffer area will be allocated from
0x20_1000 to 0x20_1EFF; the registers area will be allocated from 0x20_1F00 to 0x20_1FFF and the RX buffer area will
be allocated from 0x20_2000 to 0x20_2FFF. (Note: AX88180 only decodes low 16-bit address)
3.10 EEPROM Format
AX88180 will auto-load data from EEPROM device after hardware reset. If the EEPROM device is not attached, the
loading operation will be discarded. The EEPROM mainly provides MAC address information and CIS information if it is
used in PCMCIA environment. Below table is the format if EEPROM device is employed. Note: If the MAC address is 12
34 56 78 9A BC (MSB-LSB) then driver should set MACID0=0x9ABC, MACID1=0x5678 and MACID2=0x1234.
Address
16-bits data Description
0
Pointer to starting address of CIS area. Set this field to 0x0070 to shorten the download EEPROM if there is
no CIS needed. AX88180 only supports the 16-bit mode of 93C56, thus the max value of this field is
0x007F. This field should not be set to 0x0000 or 0xFFFF; otherwise, AX88180 will not recognize the
EEPROM during hardware reset.
1
MACID0 data
2
MACID1 data
3
MACID2 data
4
Reserved, keep all 0’s
5
Bit0: When GPIO0 is set to ‘1’ in reset stage, this bit indicates AX88180 whether it is in the environment of
PCMCIA.
0 = General 16-bit mode,
1= Special for PCMCIA environment of 16-bit mode.
Bit1: must be ‘0’
Bit2: 1 = set RGMII mode by EEPROM, 0 = none. (The setting will be cleared when software resets)
Bit3: 1 = set Gigabit mode by EEPROM, 0=none (The setting will be cleared when software resets)
Others bits must set to 0s
6 ~ 11
Reserved, keep all 0’s
12 ~ 127
CIS area, if AX88180 is used in PCMCIA system, otherwise set them to all ‘0s’
