Detailed Description

Module containing functions with core-dependent implementation, like delay.

Macro Definition Documentation

NRFX_COREDEP_DELAY_US_LOOP_CYCLES

#define NRFX_COREDEP_DELAY_US_LOOP_CYCLES   3

Number of cycles consumed by one iteration of the internal loop in the function nrfx_coredep_delay_us.

This value can be specified externally (for example, when the SoC is emulated).

Function Documentation

nrfx_coredep_delay_us()

NRF_STATIC_INLINE void nrfx_coredep_delay_us

(

uint32_t

time_us

)

Function for delaying execution for a number of microseconds.

The value of time_us is multiplied by the CPU frequency in MHz. Therefore, the delay is limited to the maximum value of the uint32_t type divided by the frequency.

Parameters

time_us

Number of microseconds to wait.
