4.1 Detailed Description
The following sections provide detailed description for some of the field in serial EEPROM memory map, for other fields
not covered here, please refer to AX88772L application note for more details.
4.1.1 Word Count for Preload (00h)
The number of words to be preloaded by the EEPROM loader = 15h.
4.1.2 Flag (01h)
4.1.3 Node ID (04~06h)
The Node ID 0 to 5 bytes represent the MAC address of the device, for example, if MAC address = 01-23-45-67-89-ABh,
then Node ID 0 = 01, Node ID 1 = 23, Node ID 2 = 45, Node ID 3 = 67, Node ID 4 = 89, and Node ID 5 = AB.
