| Concern | Mitigation | |---------|------------| | | Signature verification prevents rogue binaries. | | Electromagnetic Interference (EMI) | The PB772 firmware employs adaptive filtering and a “shield‑on‑detect” mode that reduces scan frequency when high‑frequency noise is detected. | | Touch‑Ghosting / Crosstalk | Baseline tracking combined with a per‑electrode debounce timer minimizes false contacts. | | Firmware Corruption | A dual‑bank flash layout allows rollback to a known‑good image if the active image fails integrity checks. | | Power‑Loss During Update | The boot loader writes to a temporary buffer; the active image is only replaced after a full, verified write, making the process atomic. | | Side‑Channel Leakage | The controller does not expose raw ADC values to the host in normal operation; only processed touch packets are transmitted. | Tpd.rt2841.pb772 Firmware
