Hello TI experts,
I asked about the weird operation of BQ32002 ;
i tested more about this. the result is, i cannot write to register on fault device.
1. the write on normal device, and read it;
- i write 19th may, 2001, 09:00 => 00 00 00 07 19 05 01 80 90 8a
- i write 19th may, 1988, 11:12 => 00 12 02 05 19 05 84 80 90 8a (i think it is normal operation.)
2. the write on fault device, and read it;
- i write 19th may, 2001, 09:00 => 00 7d 3f 05 1f 1f ef 80 90 aa
- i write 19th may, 1988, 11:12 => 00 7d 3f 05 1f 1f ef 80 90 aa (the result was same even i write different value.)
furthermore, this value of register is exactly same as the value that right after the device is booted. and it never changed even i enter any value.
can you give me any advice for this situation?
Best regards,
Chase
