Register descriptions

64.4.1.1 DTS output enable register (ENABLE)
The DTS_ENABLE register controls the DTS Trigger Output (DTO) and whether DTO is
active on the EVTO output pin of the device.
DTS_ENABLE register.
Note: Access to the DTS_SEMAPHORE, DTS_SEMAPHORE_B, and DTS_STARTUP registers
are unaffected by the state of this register.

The DTS_ENABLE register is described in
Field
DTS Enable. Controls whether the DTO signal is routed to the EVTO pin. The DTS Enable bit is
cleared by a device reset (either the assertion of the external RESET or by an internally generated
reset). A Nexus reset does not change the state of this register.
DTS_EN
0 DTS output disabled. Any bit set in the DTS_SEMAPHORE register does not assert the DTS trigger
output signal.
1 DTS output enabled. Any bit set in the DTS_SEMAPHORE register asserts the DTS trigger output
signal (DTO).
DTS Enable B. Controls whether the DTO signal is routed to the EVTO pin. The DTS Enable bit is
cleared by a device reset (either the assertion of the external RESET or by an internally generated
reset). A Nexus reset does not change the state of this register.
DTS_EN_B
0 DTS output disabled. Any bit set in the DTS_SEMAPHORE_B register does not assert the DTS
trigger output signal.
1 DTS output enabled. Any bit set in the DTS_SEMAPHORE_B register asserts the DTS trigger
output signal (DTO).
