66AK2G12: Unique 48-bit MAC address

JuPo
Prodigy 70 points

Part Number: 66AK2G12

Hello,

SPRUHY8H (TRM) section 5.1.3.1.15 is saying that each device has unique 48-bit MAC address which is stored in BOOTCFG_MACIDx registers......

In the same TRM Table 4-27 on lines 24, 26 and 28 default value is show as "From E-FUSE"

  1. How the MAC address is loaded into BOOTCFB registers? is it done in a production? Please clarify.
  2. Could you confirm that each individual 66AK2G12 device (not high-security device) as received from distributors has programmed unique code in a BOOTCFG_MACIDx registers?

Thank you.

Regards

Juraj
