STATUS.TXT
is dynamically updated by the on-board debugger. The contents may be cached by
the OS and, therefore, do not reflect the correct status.
3.1.3.2 Configuration Words
Configuration Words (PIC
®
MCU Targets)
Configuration Word settings included in the project being programmed after program Flash is programmed. The
debugger will not mask out any bits in the Configuration Words when writing them, but since it uses Low-Voltage
Programming mode, it is unable to clear the LVP Configuration bit. If the incorrect clock source is selected, for
example, and the board does not boot, it is always possible to perform a bulk erase (always done before
programming) and restore the device to its default settings.
3.1.3.3 Special Commands
Several utility commands are supported by copying text files to the mass storage disk. The filename or extension is
irrelevant – the command handler reacts to content only.
Table 3-2. Special File Commands
Command Content Description
CMD:ERASE Executes a chip erase of the target
CMD:SEND_UART= Sends a string of characters to the CDC UART. See “ CDC Override Mode ”.
CMD:RESET Resets the target device by entering Programming mode and then exiting
Programming mode immediately thereafter. Exact timing can vary according to
the programming interface of the target device. (Debugger firmware v1.16 or
newer.)
CMD:POWERTOGGLE 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.)
CMD:0V 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.)
CMD:3V3 Sets the target voltage to 3.3V. If external power is provided, this has no effect.
(Debugger firmware v1.16 or newer.)
CMD:5V0 Sets the target voltage to 5.0V. If external power is provided, this has no effect.
(Debugger firmware v1.16 or newer.)
Info: The commands listed here are triggered by the content being sent to the mass storage emulated
disk, and no feedback is provided in the case of either success or failure.
3.1.4 Data Gateway Interface (DGI)
Data Gateway Interface (DGI) is a USB interface for transporting raw and time-stamped data between on-board
debuggers and host computer-based visualization tools.
MPLAB Data Visualizer is used on the host computer to
display debug GPIO data. It is available as a plug-in for MPLAB
®
X IDE or a stand-alone application that can be used
in parallel with Microchip MPLAB
®
X IDE.
Although DGI encompasses several physical data interfaces, the PIC18F57Q43 Curiosity Nano implementation
includes logic analyzer channels:
• One debug GPIO channel (also known as DGI GPIO)
