Description
Sets CPU timestamp’s timer frequency, in Hertz.
Files
cpu_core.h/cpu_core.c
Prototype
Arguments
freq_hz
Frequency (in Hertz) to set for CPU timestamp’s timer.
Returned Value
None.
Required Configuration
Available only if either of the following CPU features is enabled in cpu_cfg.h :
- CPU timestamps when either
CPU_CFG_TS_32_ENorCPU_CFG_TS_64_ENisDEF_ENABLED. See Timestamps Configuration. - CPU interrupts disabled time measurements when
CPU_CFG_INT_DIS_MEAS_ENis#define'd. See Interrupts Disabled Time Measurement Configuration.
Notes / Warnings
- CPU timestamp timer frequency is not required for internal CPU timestamp operations and may optionally be configured by application/BSP initialization functions for use with optional
CPU_TS_to_uSec()functions to convert CPU timestamps from timer counts into microseconds (see CPU_TS32_to_uSec and CPU_TS64_to_uSec).
