14.15.2 File Registers Window

The File Registers window displays all the file registers of the selected device. When a file register value changes, or the processor is interrogated, the data in the File Registers window is updated (values updated shown in red).

Some data has colored cells:

  • Blue cells represent SFRs.
  • Green cells represent project variables.
  • Gray cells represent reserved memory.
Note: To speed up debugging with certain hardware tools, close this window. Use the SFR or Watches window instead.

File Registers Window Displays

You may specify how memory is displayed in the window by selecting from the Format drop-down box on the bottom of the window.

When using a hardware tool for debug, some registers may show an R for each nibble of data to represent a reserved resource.

Hex

This format displays file register information as hex data. The window has the following columns:

  • Address – Hexadecimal address of the data in the next column.
  • Data Blocks – Hexadecimal data, shown in 1- or 2-byte blocks.
  • ASCII – ASCII representation of the corresponding line of data.

Symbol

This format displays each file register symbolically with corresponding data in hex, decimal, binary and character formats. The window has the following columns:

  • Address – Data hexadecimal address.
  • Symbol Name – Symbolic name for the data.
  • Radix Information – Hex, Decimal, Binary, Char
Radix information is displayed in these four columns. Hex is shown in 1- or 2-byte blocks.

Dual Port (dsPIC33FJ DSC/PIC24HJ MCU devices only)

This format displays file register information as hex data. The window has the following columns:

  • Address – Data hexadecimal address.
  • DMA Address – Offset from the silicon DMA address.
  • Data Blocks – Hexadecimal data, shown in 1- or 2-byte blocks.
  • ASCII – ASCII representation of the corresponding line of data.

For information on dsPIC33F DSC and PIC24H MCU devices, see the Microchip website for device data sheets and the dsPIC33/PIC24 Family Reference Manual (DS-70000618, etc.)

XY Data (dsPIC DSC devices only)

This format displays file register information as hex data. The window has the following columns:

  • Address – X hexadecimal address of the data.
  • Y Bus – Y hexadecimal address of data, if supported.
  • Data Blocks – Hexadecimal data, shown in 2-byte blocks.
  • ASCII – ASCII representation of the corresponding line of data.

For more information, see the dsPIC30F Family Reference Manual (DS-70046).

Item Description
Hex Display Width Hex Format Only

Set the hexadecimal display width
 (options depend on the device selected).
Fill Memory Fill memory from Start Address to End Address with the value in Data. Specify other options in the Fill Memory dialog.
Go To Go to the address/function specified using the Go To dialog.
Find Find text specified using the Find dialog.
Output To File Write the displayed window contents to a text file using the Output to File dialog.
Import Table Hex, Dual Port or XY Data Formats Only

Import tabular data from a file into a Memory window using the Import Table dialog.
Export Table Hex, Dual Port or XY Data Formats Only

Export tabular data from a Memory window into a file using the Export Table dialog.
Print Print the contents of this window using the Print dialog.
Note: If you have a large memory device, the number of pages printed can become very large. A suggestion is to print the window contents to a file (Print dialog, General tab, Print to File check box) and then select which pages from the file you need to print.
Adjust Table Columns Adjust the columns automatically.
