Part Number:BOOSTXL-DRV8320S
Hi
Our customer evaluates DRV8320 with TI-EVM. And they have some question.
Before starting the evaluation,,They confirmed the initial value of each register. (It was ok) And they confirmed it can be written new value (0x0020) to (add:)0x02.
(There is no problem so far.)
Addr:0x00=0x0000, 0x01=0x0000, 0x02=0000, 0x03=0x03FF, 0x04=0x07ff, 0x05=0x0159
1. On the other hand, they wrote the new value (0x000) to 0x02 again. However it could not rewritten. (because the register value of respond was not 0x000. It was 0x0020.)
2. As same situation,they wrote the new value of 0x0334 to address:0x05.However the value of respond was 0x037D.
I do not uderstand why the register value was not expected register value which was written. What should we do? Or Do we need to execute anything command?
