• IO_0 is selectable as follows:

Analog input (load dump proof) sent to the MCU through the MUX_OUT pin. Wake-up input on the rising or

falling edge or based on the previous state. Digital input (logic level) sent to the MCU through the SPI.

Safety purpose: IO_0 is the only wake-up input to resume from deep fail-safe mode.

• IO_2:3 are selectable as follows:

Digital input (logic level) sent to the MCU through the SPI. Wake-up input on the rising or falling edge or based

on the previous state.

Safety purpose: Digital input (logic level) to monitor MCU error signals (both IO_2 AND

IO_3 are used if configured as safety inputs). Only bi-stable protocol is available.

When IO_2:3 are used as safety inputs to monitor FCCU error outputs from the NXP MCU, the monitoring is

active only when the fail-safe sate machine is in ’normal WD’ state (Figure 17) and all the phases except the

’normal phase’ are considered as an error.

• IO_4 is selectable as follows:

Digital input (logic level) sent to the MCU through the SPI. Wake-up input (load dump proof) on rising or falling

edge or based on previous state. Output gate driver (from VPRE) for low-side logic level MOSFET.

• IO_5 is selectable as follows:

Analog input (20 V max.) sent to the MCU through the MUX_OUT pin. Digital input (logic level) sent to the MCU

through the SPI. Wake-up input on rising or falling edge or based on previous state. VKAM output supply.

• IO_4:5 are selectable as follows:

Safety purpose: Digital input (logic level) to perform an IC error monitoring (both IO_4 AND IO_5 are used if

configured as safety inputs, see Figure 14).
