Module containing functions with core-dependent implementation, like delay.
| #define 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).
| 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.
| time_us | Number of microseconds to wait. |
