DIAG1CFG and DIAG2CFG registers (low voltage side)

The DIAG1CFG register has the structure of Table 56.

The DIAG2CFG register has the structure of Table 57.

If a bit in the DIAG1CFG register is high, the corresponding fault events turn on the open

drain connected to the DIAG1 pin forcing the output low.

If a bit in the DIAG2CFG register is high and the DIAG_EN bit is high, the corresponding

fault events turn on the open drain connected to the DIAG2 pin forcing the output low.
