I am trying to put the BQ35100 device to Unseal mode from full access mode.
I have tried the following:
1. I2C Write 3E, 04, 14 followed by I2C Write 3E, 36, 72 - fails to unseal device
2. I2C Write 3E, 14, 04 followed by I2C Write 3E, 72, 36 - fails to unseal device
3. I2C Write 00, 04, 14 followed by I2C Write 00, 36, 72 - fails to unseal device
4. I2C Write 00, 14, 04 followed by I2C Write 00, 72, 36 - fails to unseal device
5 - 8. Writing the second part first (ie 3672) followed by the first part (ie 0414).
I noticed when reading the Unseal Codes from 0x41CC - it reports 143672FF; whereas when reading from 0x41CB - it reports 4143672. Is this offset expected ? For completeness sake, I also tried the previous 4 ways with 143672FF as the unseal key instead of 04143672.
What is the correct I2C sequence I must follow? If you could give me the exact addresses to use instead of register names, that would be very useful
