  • smac_0_0/1
  • smac_1_0/1
  • smac_2_0/1
  • smac_3_0/1

Map the supplementary addresses to the respective registers in the same manner as the primary MAC address. Refer to the description of mac_0 and mac_1.

The MAC function uses the supplementary addresses for the following operations:

If you do not require the use of supplementary addresses, configure them to the primary address.
