CS89712

(Register 4, RxEvent, Bit 9) is set. See Section 2.32.7, “Receive Ethernet Port Locations”.

Reset value is: 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000

3.20.2 Individual Address (IEEE or MAC address, address offset 0158h)

Address 0015Dh

Octet 5 of IA

Address 015Ch

Address 015Bh

Address 015Ah

Address 0159h

Address 0158h

Octet 0 of IA

For example: if the MAC address is “00242010ABCD” then load register address 0158h with 00h, 0159h with 24h,

015Ah with 21h, etc.

The value of this register must be loaded from external storage, for example, from the EEPROM. See Section 2.24,

“Programming the EEPROM”. If the CS89712 is not able to load the IA from the EEPROM, then after a reset this

register is undefined, and the driver must write an address to this register.
