BQ28Z610: SEC1,SEC0 read by different command

Part Number: BQ28Z610

Sir,

by the SLUUA65C, the access status of the BQ28Z610 can be read by the command 0x00/01 or AltManufacturerCommand 0x0054.

The 1st command replies with a 2-bytes word where bits 14:13 are SEC1,SEC0; the 2nd command replies with a 4-bytes word where the same registers are at bits 14:13 and 9:8 

My SW used the direct command 0x00 but because it did not recognize the FULL ACCESS status I checked and I found something different from what is written in the literature

Below a table with the status SEALED, UNSEALED and FULL ACCESS read by the 2 different commands and the right status is in bold.

                                         0x00, bits 14:13     0x0054, bits 14:13     0x0054, bits 9:8

SEALED                                    11                               10                            11

UNSEALED                               10                               10                            10

FULL ACCESS                          00                               00                            01

Then I have know that the correct status is at the bits 9:8 when read by 0x0054 AltManufacturer command.

May you please explain me the above behavior ? and correct the SLUUA65C.....

Thanks
