Registers
Debug Status (DEBS)
Device ID Register (DID)
Nexus Configuration Register (NXCFG)
When an interrupt occurd the CPU will jump to the interrupt handler routine and process the
interrupt. The interrupt handler must clear the interrupt before leaving this routing. This is done
by witing a zero to DCEMUDI or DCCPURI for DCEMU reads and DCCPU writes respectively:
This message is output when the CPU enters or exits Debug Mode or a low-power mode. The
message is output whenever the AUX port is enabled. The STATUS field of this message con-
tains the information in the Development Status register. The field will contain these values:
Table 9-4.
The Device ID Register (DID) provides key attributes to the development tool concerning the
embedded processor. This is the same as the value returned by the JTAG ID instruction.
Table 9-5.
The Nexus Configuration Register (NXCFG) provides key information about the specific imple-
mentation of the CPU and OCD architecture, and the configuration of the Nexus development
