*
* Note(s) : (1) Configure CPU_CFG_TS_xx_EN to enable/disable CPU timestamp features :
*
* (a) CPU_CFG_TS_32_EN enable/disable 32-bit CPU timestamp feature
* (b) CPU_CFG_TS_64_EN enable/disable 64-bit CPU timestamp feature
*
* (2) (a) Configure CPU_CFG_TS_TMR_SIZE with the CPU timestamp timer's word size :
*
* CPU_WORD_SIZE_08 8-bit word size
* CPU_WORD_SIZE_16 16-bit word size
* CPU_WORD_SIZE_32 32-bit word size
* CPU_WORD_SIZE_64 64-bit word size
*
* (b) If the size of the CPU timestamp timer is not a binary multiple of 8-bit octets
* (e.g. 20-bits or even 24-bits), then the next lower, binary-multiple octet word
* size SHOULD be configured (e.g. to 16-bits). However, the minimum supported word
* size for CPU timestamp timers is 8-bits.
*
* See also 'cpu_core.h FUNCTION PROTOTYPES CPU_TS_TmrRd() Note #2a'.

* CPU INTERRUPTS DISABLED TIME MEASUREMENT CONFIGURATION
*
* Note(s) : (1) (a) Configure CPU_CFG_INT_DIS_MEAS_EN to enable/disable measuring CPU's interrupts
* disabled time :

*
* (b) Configure CPU_CFG_INT_DIS_MEAS_OVRHD_NBR with the number of times to measure &
* average the interrupts disabled time measurements overhead.
*
* Recommend a single (1) overhead time measurement, even for instruction-cache-enabled
* CPUs, since critical sections are NOT typically called within instruction-cached loops.
* Thus a single non-cached/non-averaged time measurement is a more realistic overhead
* for the majority of non-cached interrupts disabled time measurements.
*
* See also 'cpu_core.c CPU_IntDisMeasInit() Note #3a'.
