Detailed Description

Macro Definition Documentation

◆ CRITICAL_REGION_ENTER

#define CRITICAL_REGION_ENTER ( )

Value:

{                                                                            \
        uint8_t __CR_ENTERED = 0;                                                \
        nrf_util_critical_region_enter(&__CR_ENTERED);

Note: CRITICAL_REGION_EXIT() and CRITICAL_REGION_ENTER() must exist in pairs with enter before the exit and they must be located in the same scope.

Definition at line 103 of file nrf_util.h.

◆ CRITICAL_REGION_EXIT

#define CRITICAL_REGION_EXIT ( )

Value:

nrf_util_critical_region_exit(__CR_ENTERED); \

}

Note: CRITICAL_REGION_EXIT() and CRITICAL_REGION_ENTER() must exist in pairs with enter before the exit and they must be located in the same scope.

Definition at line 113 of file nrf_util.h.

◆ LFCLK_FREQ

#define LFCLK_FREQ 32768

Marco that defines the LFCLK frequency

Definition at line 84 of file nrf_util.h.

◆ LFCLK_TICKS_1250

#define LFCLK_TICKS_1250 ( ms ) ((uint32_t) ROUNDED_DIV( (LFCLK_FREQ*(uint64_t)ms) , 800) )

Macro to find out the number of LFCLK ticks for the passed time in multiples of 1.25 ms

Definition at line 93 of file nrf_util.h.

◆ LFCLK_TICKS_625

#define LFCLK_TICKS_625 ( ms ) ((uint32_t) ROUNDED_DIV( (LFCLK_FREQ*(uint64_t)ms) , 1600) )

Macro to find out the number of LFCLK ticks for the passed time in multiples of 0.625 ms

Definition at line 89 of file nrf_util.h.

◆ LFCLK_TICKS_977

#define LFCLK_TICKS_977 ( ms ) ((uint32_t) (32*ms) )

Definition at line 91 of file nrf_util.h.

◆ LFCLK_TICKS_MS

#define LFCLK_TICKS_MS ( ms ) ((uint32_t) ROUNDED_DIV( (LFCLK_FREQ*(uint64_t)ms) , 1000) )

Macro to find out the number of LFCLK ticks for the passed time in milli-seconds

Definition at line 87 of file nrf_util.h.
