Initialization of ADE7880

I am working on a PQM system and to lighten the development process, use an 8-channel logic analyzer to track the SPI protocol between the evaluation board and the ADE7880 chip, everything is fine, I understand, but there are two records that are read in initialization, whose addresses are: 0xEC09 and 0xEC06. These records do not appear on the map of records, because it reaches 0xEC01, someone would know how to tell me the function of these records please.
