5.2. DIAG output
DIAG1 and DIAG2 are open-drain-type output pins. Insert pull-up resistors between these pins and VDDIO (MCU power supply). If no SPI communication is used, connect the VDDIO pin and the external pull-up resistors, that is connected at DIAG1 and DIAG2, to the VCC power supply. When the following faults are detected, these pins outputs L. In the following table, X: Don't Care, H: High, L: Low, and Hiz: High Impedance.
