P R E L I M INARY

pose 8-bit register that is loaded from the EE-

PROM.

Node IP Address 1 (MReg Address 16)

This register is loaded from the EEPROM.

Bit No.

Name and Description

7:0

N_IP_ADR[15:8]

Default: 00h Read only, write has no effect.

Byte 1 of the Node IP Address register. The

Node IP Address is the 32-bit address used in

the IP protocol header to address the station,

the Am79C975 controller is used in. This reg-

ister can also be used as general purpose 8-bit

Node IP Address 2 (MReg Address 17)

This register is loaded from the EEPROM.

Bit No.

Name and Description

7:0

N_IP_ADR[23:16]

Default: 00h Read only, write has no effect.

Byte 2 of the Node IP Address register. The

Node IP Address is the 32-bit address used in

the IP protocol header to address the station,

the Am79C975 controller is used in. This reg-

ister can also be used as general purpose 8-bit

Management Station IP Address 3 (MReg Address

18)

This register is loaded from the EEPROM.

Bit No.

Name and Description

7:0

N_IP_ADR[31:24]

Default: 00h Read only, write has no effect.

Byte 3 (the MSB) of the Node IP Address reg-

ister. The Node IP Address is the 32-bit ad-

dress used in the IP protocol header to

address the station, the Am79C975 controller

is used in. This register can also be used as

general purpose 8-bit register that is loaded

from the EEPROM.

Management Station IEEE Address 0 (MReg

Address 19)

This register is loaded from the EEPROM.

Bit No.

Name and Description

7:0

M_IEEE_ADR[7:0]Default:

00hRead

only,

write has no effect.

Byte 0 (the LSB) of the Management Station

IEEE Address register. The Management Sta-

tion IEEE Address is the unique 48-bit address

of the station that is used as the management

console in the network. This register can also

be used as general purpose 8-bit register that

is loaded from the EEPROM.

Management Station IEEE Address 1 (MReg

Address 20)

This register is loaded from the EEPROM.

Bit No.

Name and Description

7:0

M_IEEE_ADR[15:8]

Default: 00h Read only, write has no effect.

Byte 1 of the Management Station IEEE Ad-

dress register. The Management Station IEEE

Address is the unique 48-bit address of the

station that is used as the management con-

sole in the network. This register can also be

used as general purpose 8-bit register that is

loaded from the EEPROM.

Management Station IEEE Address 2 (MReg

Address 21)

This register is loaded from the EEPROM.

Bit No.

Name and Description

7:0

M_IEEE_ADR[23:16]

Default: 00h Read only, write has no effect.

Byte 2 of the Management Station IEEE Ad-

dress register. The Management Station IEEE

Address is the unique 48-bit address of the

station that is used as the management con-

sole in the network. This register can also be

used as general purpose 8-bit register that is

loaded from the EEPROM.

Management Station IEEE Address 3 (MReg

Address 22)

This register is loaded from the EEPROM.

Bit No.

Name and Description

7:0

M_IEEE_ADR[31:24]

Default: 00h Read only, write has no effect.

Byte 3 of the Management Station IEEE Ad-

dress register. The Management Station IEEE

Address is the unique 48-bit address of the

station that is used as the management con-

sole in the network. This register can also be

used as general purpose 8-bit register that is

loaded from the EEPROM.
