  "textContent": "According to an embodiment, a deployment circuit for controlling the deployment of a pyrotechnic device includes a deployment driver circuit configured to energize the pyrotechnic device, diagnostic circuitry configured to perform diagnostic controls, a communication interface couplable to a microcontroller, a fault signal terminal, and a control circuit comprising a hardware Finite-State Machine. The control circuit executes diagnostic routines, each comprising a sequence of diagnostic operations. In each diagnostic operation, the control circuit generates control signals for the diagnostic circuitry, monitors signals from the diagnostic circuitry, determines whether the signals indicate faults, and, upon detecting faults, asserts the fault signal and stores a fault code. The control circuit receives a request from the microcontroller via the communication interface and transmits the stored fault code, enabling autonomous diagnostic operation with minimal microcontroller intervention.",
