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_EN or CPU_CFG_TS_64_EN is DEF_ENABLED (see section 6-1)
  • CPU interrupts disabled time measurements when CPU_CFG_INT_DIS_MEAS_EN is #define'd (see section 7-1)

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()).

Example Usage
