Show Processor Pins
The Processor Pins dialog box is a convenient tool for monitoring the current state of the
processor pins, as well as the peripheral with which a pin may be associated. The
processor is represented, in graphical form, in the middle of the dialog box. Each pin is
labeled with its current function. For example, Pin 2 is the BKGD pin upon reset.
However, with the appropriate write to the SOPT register, the user can observe that Pin 2
changes to PTA3 in the Processor Pins dialog box.
In the dialog box, each processor pin (with the exception of the power pins, Vdd and
GND) has a corresponding arrow. If the arrow points towards the processor, this indicates
that the pin is configured as an input. Conversely, if the arrow is pointing away from the
processor, this indicates that the pin is configured as an output.
Figure 25.9 Processor Pins Window
Below the graphical processor representation are several buttons, each corresponding to a
processor peripheral. Pressing the button of a given peripheral brings up the appropriate
register files (see below), allowing for easy and informative manipulation of all status,
control, and data bits associated with a peripheral.
At the bottom of the dialog box is a reading of the current processor speed. This is
measured on the device itself, and is a real-time indication of the current bus speed of the
processor.
View Register Files Option
The View Register Files Connection menu selection also gives the user the option of
running the register file viewer/editor. If register files are available for the device that you
chose, the Choose a Register Block window (see
Figure 25.10 ) opens. You may also open
it by entering the R command in the Command Window command line.
