I use S12ZVM BLDC Sensorless application.
I change the code that External clock 4MHz, 100/50 MHz CPU/Bus clock, 8.33 MHz ADC clock.
// External clock 4MHz, 100/50 MHz CPU/Bus clock, 8.33 MHz ADC clock
#define _EXTERNAL_CLOCK
#define CPMU_REFDIV 1
#define CPMU_SYNDIV 24
#define CPMU_POSTDIV 0
#define CPMU_REFFRQ 0
#define CPMU_VCOFRQ 3
#define ADC_TIM 2
#define MIN_ADC_TRIGGER_FIRST 24
#define MIN_ADC_TRIGGER_SECOND 144
#define PWM_MODULO 5000
#define PWM_DEADTIME 50
#define TIM_PRESCALER 6 // Timer prescaler 64; 50 MHz/64 = 1.28 us
#define TIMER_1MS 781
#define SCI_BAUDRATE 5208
*/
I wonder how can fix the code.
PR_SECTION(ptuTrigE)
volatile short PTUTriggerEventList[PTU_TOT_TRIGGERs_GEN_NO][PTU_TOT_LISTS_NO][3] = {
{ /*DelayT0 */
{0x0100,0x0200,0x0000},{0x0000,0x0000,0x0000}
},
{
{0x0100,0x0000,0x0000},{0x0000,0x0000,0x0000}
}
};
I use 300W ,13.5V motor.
And Sddenly motor stop situation is ocuured (during 1 minute runing Ok). GDUF = 0x33.
I use External clock 4MHz, 50/12.5 MHz CPU/Bus clock, 8.33 MHz ADC clock (original code).
Is it probelm?
I think problem is low bus clock.
And I try use External clock 4MHz, 25/12.5 MHz CPU/Bus clock, 6.25 MHz ADC clock.
Is it righ?
