DEAD_TIME_HALF

#define DEAD_TIME_HALF

(

deadTime

)

Value:

(((uint8_t)(ceil((double)deadTime * F_HST / ((double)CHOOSE_DT_PRESCALER(deadTime) * 1000000000)))))

This value specifies half the dead time in number of clock cycles. Divide by frequency to get duration.

DT_PRESCALER_DIV_PATTERN

#define DT_PRESCALER_DIV_PATTERN

(

dtPrescaler

)

Value:

   ((dtPrescaler) == 1 ? DT_PRESCALER_DIV_1 : (dtPrescaler) == 2 ? DT_PRESCALER_DIV_2 \
                                          : (dtPrescaler) == 4   ? DT_PRESCALER_DIV_4 \
                                          : (dtPrescaler) == 8   ? DT_PRESCALER_DIV_8 \
                                                                 : 0)

Deadtime generator pre-scaler selection bits based on pre-scaler value.

This macro generates the deadtime generator pre-scaler selection bits pattern based on the chosen pre-scaler value.

TIM3_TOP

#define TIM3_TOP   (((F_CPU / TIM3_FREQ / 3) >> 4) - 1)

Calculated top value for Timer 3.

Formula: TIM3_TOP = (F_CPU / (TIM3_FREQ * TIM3_PRESCALER * 6)) - 1, where TIM3_PRESCALER = 8 and 6 is the number of commutations in a complete cycle.

Definition at line 1180 of file config.h.

TIM3_TOP_MAX

#define TIM3_TOP_MAX   0xffff

Maximum top value for Timer 3.

Definition at line 1183 of file config.h.

TIM4_PRESCALER_DIV_PATTERN

#define TIM4_PRESCALER_DIV_PATTERN

(

tim4Prescaler

)

Value:

   ((tim4Prescaler) == 1 ? TIM4_PRESCALER_DIV_1 : (tim4Prescaler) == 2 ? TIM4_PRESCALER_DIV_2 \
                                              : (tim4Prescaler) == 4   ? TIM4_PRESCALER_DIV_4 \
                                                                       : 0)

Timer 4 clock select bits based on pre-scaler value.

This macro generates the timer 4 clock select bits pattern based on the chosen pre-scaler value. It is used to configure the timer's clock division.

TIM4_TOP

#define TIM4_TOP

(

tim4Freq

)

Value:

(((F_HST / ((uint32_t)tim4Freq * CHOOSE_TIM4_PRESCALER(tim4Freq))) >> 1) - 1)

Calculate top value for Timer 4. Formula: TIM4_TOP = (F_HST / (TIM4_FREQ * TIM4_PRESCALER * 2)).

Definition at line 1151 of file config.h.

TIM4_TOP_MAX

#define TIM4_TOP_MAX   0x03ff
