Function Documentation
◆ clock_set_lfclk_src()
| void clock_set_lfclk_src | ( | enum clock_lfclk_src | lfclk_src | ) |
Low Frequency Clock Source.
- Parameters
-
[in] lfclk_src enum clock_lfclk_src
Definition at line 78 of file clock_common.c.
References CLOCK_LFCLKSRC.
◆ clock_set_xtal_freq()
| void clock_set_xtal_freq | ( | enum clock_xtal_freq | freq | ) |
Select nominal frequency of external crystal for HFCLK.
This register has to match the actual crystal used in design to enable correct behaviour.
- Parameters
-
[in] freq enum clock_xtal_freq
Definition at line 40 of file clock.c.
References CLOCK_XTALFREQ.
◆ clock_start_hfclk()
| void clock_start_hfclk | ( | bool | wait | ) |
Start High Frequency Crystal Oscillator.
Oscillator needs to be running for the radio to work.
- Parameters
-
[in] wait bool If true, will busy wait for the clock to start.
Definition at line 60 of file clock_common.c.
References CLOCK_HFCLKSTAT, CLOCK_HFCLKSTAT_STATE, CLOCK_TASK_HFCLKSTART, and PERIPH_TRIGGER_TASK.
◆ clock_start_lfclk()
| void clock_start_lfclk | ( | bool | wait | ) |
Start Low Frequency Clock.
- Parameters
-
[in] wait bool: If true, will busy wait for the clock to start.
Definition at line 40 of file clock_common.c.
References CLOCK_LFCLKSTAT, CLOCK_LFCLKSTAT_STATE, CLOCK_TASK_LFCLKSTART, and PERIPH_TRIGGER_TASK.
◆ clock_stop_hfclk()
| void clock_stop_hfclk | ( | void | ) |
Stop High Frequency Crystal Oscillator.
Definition at line 69 of file clock_common.c.
References CLOCK_TASK_HFCLKSTOP, and PERIPH_TRIGGER_TASK.
◆ clock_stop_lfclk()
| void clock_stop_lfclk | ( | void | ) |
Stop Low Frequency Clock.
Definition at line 49 of file clock_common.c.
References CLOCK_TASK_LFCLKSTOP, and PERIPH_TRIGGER_TASK.
