Function
Reset Input/Output; open drain output, integrated pull-up resistor; active low.
SPI Chip Select Not Input; CSN is an active low input; serial communication is
enabled by pulling the CSN terminal low; CSN input should be set to low only when
CLK is low; CSN has an internal pull-up resistor and requires CMOS logic level
inputs.
SPI Clock Input; clock input for shift register; CLK has an internal pull-down resistor
and requires CMOS logic level inputs.
SPI Data Input; receives serial data from the control device; serial data transmitted
to SDI is a 16-bit control word with the Least Significant Bit (LSB) transferred first:
the input has a pull-down resistor and requires CMOS logic level inputs; SDI will
accept data on the falling edge of the CLK signal.
SPI Data Output; this tri-state output transfers diagnostic data to the control device;
the output will remain tri-stated unless the device is selected by a low on Chip Select
Not (CSN).
Ground
Not connected
Power Supply Input; block to GND directly at the IC with ceramic capacitor. Ensure
to have no current flow from PIN8 to PIN9. PIN8 and PIN9 can be directly connected.

External PNP Output Voltage
Interrupt Output, configuration Input; used as wake-up flag from SBC Stop Mode
and indicating failures. Active low. Integrated pull up. During start-up used to set the
SBC configuration. External Pull-up sets config 1/3, no external Pull-up sets config
2/4.
Voltage Regulator Output; 5 V supply; to stabilize block to GND with an external
capacitor.

capacitor.
Supply Input; for the internal HS CAN cell.
CAN High Line; High in dominant state.
Termination Output; to support recessive voltage level of the bus lines.
CAN Low Line; Low in dominant state.
Ground
CAN Transmit Data Input; integrated pull-up resistor.
