TMS320F280260: CPU Timer questions - 25MHz operation? external timer reset?

Expert 4185 points

Part Number: TMS320F280260


can the CPU Timers be configured for 25MHz operation?
Can the timers be reseted (ie restarted) with an external input signal? Or would you need to do the workaround to trigger an interrupt on an external input signal and reset the timer by SW?


  • Are you asking if the timer input clock can be 25 MHz? You can use the TPR register to do that if you run the CPU at a multiple of 25 MHz. Having the timers roll over at 25 MHz wouldn't be useful, since it would take longer than one timer countdown for the CPU to respond.

    The timers cannot be reset with an external signal. You'll have to use an external interrupt or some other function to alert the CPU.
