2803x CPU Timers 1 & 2

With a 2803x how do you enable use of CPU Timers 1 & 2 for an application?  The project  I’m working on does not require the DSP BIOS or other add on Realtime code and need these two timers.  CCSV5 will not let me change the registers associated them and the code in my initialization routine appears to be blocked from doing any manipulation of Timer 1 or 2 registers.

    Kim,

    There is nothing special that you have to do.  It seems to work OK for me. I can configure the timers in code, and also change the registers in CCSv5.5 in the 'Registers' View (View->Registers).  You must have something else going on in your system.

    Attached is my code example.  It is just a RAM example (need CCS to download the code to RAM).  If you run it, you will get halted in the INT13 ISR by the ESTOP0 instruction.  This indicates Timer1 is working and triggering the interrupt.

    Regards,

    David
