AM2612: Logic for combining safety inputs

Part Number: AM2612

Hello team,

is there any logic in the device that can combine multiple inputs like temperature, clock failore or "safe torque off" by XOR and outputting it to one GPIO?

Best regards

AM2612 does not have a dedicated hardware XOR combiner that natively XORs signals like temperature fault, clock failure, and Safe Torque Off (STO) into a single GPIO.

SOme options can be

- ESM that aggregates various safety-relevant fault events (temperature, clock failure, watchdog, etc.) and can drive an error output pin. This is typically OR-based, not XOR.

- XBAR (Crossbar) that can route internal signals (interrupts, fault events) to GPIO outputs — but XOR gating is generally not a native feature.

What's the ICSS usage in this project? PRU could be an option. For eg:- AM263x MCU+ SDK: EPWM protection solution using PRU
