General Set Up
MPLAB ICE communicates in bi-directional mode if it is supported by the LPT
port. However, if the host PC has difficulties communicating across the LPT
port, try communicating in compatibility mode. To force compatibility mode
communications, mark the Force Compatibility Mode checkbox. Also, verify
the LPT port type by examining the BIOS for a parallel port that is on the PC’s
motherboard or by examining the jumpers for a parallel port add-in card.
If communications difficulties persist, refer to Chapter 8.
Click Apply to accept the setting in this tab of the dialog.
4.5 Selecting the Development Mode and Processor
To select the MPLAB ICE emulator for the development mode, select the
Tools tab of the Development Mode dialog and click MPLAB ICE Emulator.
Figure 4.3: Development Mode Dialog – Tools Tab
When MPLAB ICE Emulator is selected, the processor module is queried to
determine which processor it was last configured to emulate. Since most
processor modules can emulate several different processors, this may need
to be changed. The list of selectable processors is available in the Processor
pull-down list. Select the desired processor.
Note: Compatibility mode communications will be slower than bi-direc-
tional. It is recommended that this mode be used only if bi-direc-
tional communication is not possible.
WARNING
Do not select the MPLAB ICE Emulator mode if any
other device (i.e., printer, Zip drive, scanner) is installed
on the parallel port or permanent damage to that
device may result.
