Core-dependent functionality

group nrfx_coredep

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

Defines

NRFX_DELAY_CPU_FREQ_MHZ

Core frequency (in MHz).

NRFX_DELAY_DWT_PRESENT

Availability of Data Watchpoint and Trace (DWT) unit in the given SoC.

NRFX_COREDEP_DELAY_US_LOOP_CYCLES

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).

Functions

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.

See

NRFX_COREDEP_DELAY_US_LOOP_CYCLES

Parameters

• time_us – Number of microseconds to wait.
