3.1.4 Data Gateway Interface (DGI)
Data Gateway Interface (DGI) is a USB interface for transporting raw and timestamped data between on-board
debuggers and host computer-based visualization tools.
display debug GPIO data. It is available as a plug-in for MPLAB
in parallel with MPLAB
Although DGI encompasses several physical data interfaces, the ATtiny1607 Curiosity Nano implementation includes
logic analyzer channels:
• Two debug GPIO channels (also known as DGI GPIO)
3.1.4.1 Debug GPIO
Debug GPIO channels are timestamped digital signal lines connecting the target application to a host computer
visualization application. They are typically used to plot the occurrence of low-frequency events on a time-axis – for
example, when certain application state transitions occur.
The figure below shows the monitoring of the digital state of a mechanical switch connected to a debug GPIO in
MPLAB Data Visualizer.

Description
Executes a chip erase of the target
Sends a string of characters to the CDC UART. See
Override Mode."
Sends a string of characters to the CDC UART at the baud rate
specified. Note that only the baud rates explicitly specified here
are supported! See "CDC Override
v1.21 or newer.)
Resets the target device by entering Programming mode and
then exiting Programming mode immediately afterward. Exact
timing can vary according to the programming interface of the
target device. (Debugger firmware v1.16 or newer.)
Powers down the target and restores power after a 100 ms
delay. If external power is provided, this has no effect.
(Debugger firmware v1.16 or newer.)
Powers down the target device by disabling the target supply
regulator. If external power is provided, this has no effect.
(Debugger firmware v1.16 or newer.)
Sets the target voltage to 1.8V. If external power is provided,
this has no effect. (Debugger firmware v1.21 or newer.)
Sets the target voltage to 3.3V. If external power is provided,
this has no effect. (Debugger firmware v1.16 or newer.)
Sets the target voltage to 5.0V. If external power is provided,
this has no effect. (Debugger firmware v1.16 or newer.)
