1. The DTS_STARTUP register can be read by the core, the eDMA module and Nexus but can only be updated by a Nexus
Read Write Access (RWA).
The DTS_STARTUP register is described in
Field
Application Dependent register bits. The bits have no defined meaning to the microcontroller.
They are used to by an external tool to pass information (for example, application options and
status) to application software running on target microcontroller at startup time. Use a Nexus
RWA 32-bit write access to update the contents of this register.
AD
A device reset (either from the RESET pin or an internally generated reset) clears all bits in
the register. A Nexus reset does not change the contents of the register.

register is used by software to assert the DTO signal on the device EVTO pin. A one in any
bit of this register causes the DTO signal on the EVTO pin to be driven low. The intended
use of this register is for the DTO signal to notify tools that data is available. Individual bits
are used to identify the specific data.
