Debugger Access Level

The Debugger Access Level (DSU STATUSB.DAL) defines the access rights of a debugger connected to the device.

DAL can be set to a lower setting using a SDAL command (CTRLA register).
Important: Issuing a SDAL command to set a higher setting for DAL will set INTFLAG.PROGE.

Only a Chip Erase can change DAL to a higher setting.
