Of the three external tamper pins available on the STM32MP15, only the following lines are available on the ConnectCore MP15, multiplexed with other functionality:
| GPIO | Tamper pin | Notes |
|---|---|---|
GPIOC_IO01 |
TAMP_IN3 |
Used on the ConnectCore MP15 Development Kit for ETH1_MDC |
GPIOI_IO08 |
TAMP_IN2 / TAMP_OUT3 |

| To use a pad as tamper pin, you must disable drivers with multiplexed functionality on the default device tree. |
