DSP/BIOS and timer interrupts

Robert Applebee

I am using a C5515 along with DSP/BIOS.  The C5515 has three timer/counters but only one interrupt line to the CPU.  Since the DSP/BIOS uses one of the timers for the CLK module, it has defined the ISR for the timer interrupt.  Does the ISR for the DSP/BIOS support the other two timer interrupts?

    Hi Robert,

    You're right; the ISR has been defined for the timer interrupt used for the CLK module. However, that interrupt is shared between the three timers. You will need to explicitly configure the additional timers with CLK_setTimerFunc() to be able to use this interrupt. For more information please refer to the API: http://www.ti.com/litv/pdf/spru404p (Page 588 and pg 84). Note that this is for the 5505, but the timer functionality is the same for the 5515.
