In TIDA-01093, Alert signals from upper and bottom device are routed to the MCU respectively, but they use same port of MCU and shares the same interrupt source, so they can be managed simultaneously.

But as per the circuit diagram ALERT_U and ALERT_B signals connected to MCU pins 35&36 respectively. Kindly explain the implementation logic

pin 34 and pin 36 are of the same port, so they share the same internal MCU interrupt for this port, this is why the pin status can be read simultaneously
