Items of note are:
1. Each debugger contains a unique identifier which, when first installed, will be rec-
ognized by the operating system, regardless of which computer USB port is
used.
2. MPLAB X IDE operation connects to the hardware tool at runtime (Run or Debug
Run). To always be connected to the hardware tool, see Tools>Options
, Embed-
ded button, Generic Settings tab, “Maintain active connection to hardware tool”
check box.
3. Configuration bits can only be viewed in the Configuration Bits window. To set
them in code, select Window>Target Memory Views
. Then select “Configuration
Bits” from the Memory drop list and select “Read/Write” from the Format drop list
to enable access to the settings.
3.3 DEBUG TUTORIAL
Refer to the MPLAB X IDE Help file titled “Getting Started with MPLAB X IDE,” and
navigate through the “Tutorial” to the “Running and Debugging Code.”
