CPU_TS_TmrFreqSet

Description

Sets CPU timestamp’s timer frequency, in Hertz.

Files

cpu_core.h/cpu_core.c

Prototype

          void  CPU_TS_TmrFreqSet (CPU_TS_TMR_FREQ  freq_hz);

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 Timestamps Configuration.
• CPU interrupts disabled time measurements when CPU_CFG_INT_DIS_MEAS_EN is #define'd. See Interrupts Disabled Time Measurement Configuration.

Notes / Warnings

1. 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

          CPU_TS_TmrFreqSet(2500000u);  /* Set CPU timestamp timer frequency to 2.5 MHz. */
