The DTS_ENABLE register can be read by the e200z4 core, but can only be written by a Nexus Read Write Access
(RWA).
Name
31
DTS Enable
DTS_EN
Controls whether the DTO signal is routed to the EVTO pin.
0: DTS output is disabled.
1: DTS output is enabled. Any bit set in the DTS_SEMAPHORE register will assert the DTS Trigger
Output signal (DTO).
Note: The DTS Enable bit is cleared by a device reset (either the assertion of the external RESET
or by an internally generated reset). A JTAG reset does not change the state of this register.

DTS Startup Register (DTS_STARTUP)
The DTS_STARTUP register is used for tool detection and startup information exchange between the tool
and software running on the microcontroller.
