leaps_mac_addr_set_once
Writes MAC address list to OTP memory and must be used carefully! The values cannot be modified after they have been written! It is intended to be used in the production phase to provide a MAC address pool for the device to be used by UWB, BLE, Ethernet or Wi-Fi interface. Currently the list of the MAC addresses is assigned to various interfaces as follows:
MAC address 0 is assigned to the UWB interface. Two least significant bytes must not be equal to 0x0000 or to 0xFFFF.
MAC address 1 is assigned to the BLE interface. The address will be used as the Public BLE address.
MAC address 2 and MAC address 3 are assigned to the Ethernet and to the Wi-Fi interface respectively. The address should be in th EUI-48 format respecting the LAA/UAA bit and the U/I bit.
mac_addr_0: ? 48-bits value ? (UWB MAC address in little endian)
mac_addr_1: ? 48-bits value ? (BLE MAC address in little endian)
mac_addr_2: ? 48-bits value ? (Ethernet MAC address in little endian)
mac_addr_3: ? 48-bits value ? (WIFI MAC address in little endian)
