I am testing the BQ27621-G1 using eval board (together with the EV2400 USP to SPI converter). Everything is working (reading/writing data memory, toggle powermin, ....) as expected except the 'sealed' command. It seems that this command is simply ignored. The status of the 'SS' bit in the control status register is not changing and all commands that should not be available in the sealed mode are still working after sending this command...
Even after a full device reset followed directly by a sealed command the access mode is not changing...
Is there any special sequence necessary to place the BG27621 in sealed access mode or is there any chip status that prevents to switch the access mode?
Thank's for help
Thomas
