Development Status Register (DS)

The Development Status Register is used to report system debug status. When Debug
Mode is entered or exited, or an SoC- or core-defined Low Power Mode is entered (see note
below), a Debug Status Message is transmitted with DS[31:24]. The external tool can read
this register at any time.
