Part Number: TMS320F2812

Tool/software: TI C/C++ Compiler

I'm looking at some code that was written for TMS320F2812. One of the instructions line has a single instruction:

ERTM;

The comment says:

// Enable Global realtime debug DBGM.

I could not find document for this. Anyone knows where I can find any information on this?

Paul,

ERTM is defined in a header file somewhere in your project, likely "DSP281x_Device.h":
#define ERTM asm(" clrc DBGM")

The instruction clears a bit in status register ST1 to enable real-time debug mode in the core. You can read more about this in Section 2.4 of the "CPU and Instruction Set Reference Guide".

There is an online video which might help, here:

There is a training workshop which might be of interest, especially module 6:

Regards,

Richard
