EMB1428Q: EMB1428 SPI fine, but not close

Part Number: EMB1428Q

Hi,

I sent 0xF0 to EMB1428 and it return 0xAF. But only PSW3 is close. CSW7 to 0 are all open.

I've set 1499 FAULT PIN to 0.

And I saw someone got similar problem before. But TI FAE said 0xAF(Fault code 1010 is 1499 fault)

Please let me know which is correct.

BR,

Troy
