/**
* @brief Get GPTimer captured count value
*
* @note The capture action can be issued either by ETM event or by software (see also `gptimer_get_raw_count`).
* @note Different from `gptimer_get_raw_count`, this function won't trigger a software capture event. It just returns the last captured count value.
* It's especially useful when the capture has already been triggered by an external event and you want to read the captured value.
* @note This function is allowed to run within ISR context
* @note If `CONFIG_GPTIMER_CTRL_FUNC_IN_IRAM` is enabled, this function will be placed in the IRAM by linker,
* makes it possible to execute even when the Flash Cache is disabled.
