SWD security level 2 configures the device in a maximally restrictive state. The physical debug port (SW-DP) is completely disabled, and all of the SWD-accessible functions (application debug, mass erase, factory reset, and TI failure analysis) are not accessible through SWD, regardless of their individual configuration.
When level 2 is selected (SW-DP disabled), the application debug configuration and TI failure analysis configuration fields are don't care fields which do not impact the device configuration.
If the BSL is disabled, then the mass erase and factory reset configuration fields are also don't care fields. However, if the BSL is enabled, then the mass erase and factory reset configuration fields are still used by the BSL to authorize mass erase or factory reset commands originating from the BSL interface.
When to Use This State
Use Level 2 only for mass production when no further access to any SWD functions is required and a maximally secure state is desired for the device.
When to Not Use this State
Do not use Level 2 in the following cases:
