  • TMS320F28069: Interrupt latency jitter introduced by low priority interrupt in high priority ISR call

    Resolved
    Part Number: TMS320F28069 The attached code uses PWM2 to generate some test pulses of fixed frequency,10kHz and fixed duty cycle (40%). The pulses are read in on GPIO13. XINT1 is enabled on GPIO13 with rising edge detection ON. So whenever the PWM2 pulse…
