MPLAB ? REAL ICE ? IN-CIRCUIT
EMULATOR USER ’S GUIDE
Chapter 8. Debug for 32-Bit Devices
8.1
8.2
8.3
INTRODUCTION
The following debug functions are specific to 32-bit devices:
? Data Capture and Runtime Watches
? PIC32 Instruction Trace
DATA CAPTURE AND RUNTIME WATCHES
At this time, MPLAB REAL ICE in-circuit emulator does not support data capture for
32-bit devices. Runtime watches, however, are supported.
A runtime watch provides updating of a variable in the following windows during
program execution instead of on halt:
? Watch – View menu
? File Register – View menu
? Special Function Register (SFR) – View menu
To set up runtime watches:
1. Select View>Watch to open the Watch window to set up runtime watches for
specific data addresses. See Section 11.3.9 “Watch Window - Data Cap-
ture/Runtime Watch” for more information.
2. Select Debugger>Settings and click the Clock tab. The emulator needs to know
the instruction cycle speed. (See Section 11.5.6 “Settings Dialog, Clock Tab”
for more information.) Enter your information here.
3. Rebuild the project ( Project>Build All ) and reprogram the target device
( Debugger>Program ).
4. Run the program. Watch variable values change in an MPLAB IDE window.
PIC32 INSTRUCTION TRACE
This section will discuss trace for 32-bit devices and how to use it.
? Requirements for Trace
? Setting Up and Using Trace
? Trace Hardware Specifications
8.3.1
Requirements for Trace
The following is required to use trace for 32-bit (PIC32MX) devices:
? MPLAB IDE v8.00 and above
? MPLAB ASM32/LINK32/C32 v1.00 and above
? PIC32MX Plug-In Module (PIM) containing a device that supports trace and a
trace port
? PIC32MX Trace Interface Kit (AC244006) containing a 12-inch trace cable and a
trace adapter board
? 2008 Microchip Technology Inc.
