Regarding Pin 14 "Pin" DIAG_EN "Low, I'd like to know how it will behave.

According to Table 1 of the data sheet, the port at Low / ST1 to ST4 does not operate.

The protection function is determined by the state of INx.

When INx is H, it is full protection. Which functions are active?

When INx is L, it is described as no protection, which function loss.

I appreciate your great help in advance.

Best regards,
