[1] Pin BOOT should not be loaded by any other means than the boot capacitor. Shorting pin BOOT to VSS will damage the device.
[2] Pin STABI should not be loaded by an external circuit. Shorting pin STABI to a voltage source or VSS will damage the device.
[3] Pin DIAG should not be connected to a voltage source or to a pull-up resistor. An example of a circuit that can be used to read out
diagnostic data is given in Figure 7.
