* ULP coprocessor starts running the program when the wakeup timer counts up
* to a given value (called period). There are 5 period values which can be
* programmed into SENS_ULP_CP_SLEEP_CYCx_REG registers, x = 0..4.
* By default, wakeup timer will use the period set into SENS_ULP_CP_SLEEP_CYC0_REG,
* programmed into SENS_ULP_CP_SLEEP_CYCx_REG registers, x = 0..4 for ESP32, and
* one period value which can be programmed into RTC_CNTL_ULP_CP_TIMER_1_REG register for ESP32-S2.
* By default, for ESP32, wakeup timer will use the period set into SENS_ULP_CP_SLEEP_CYC0_REG,
* i.e. period number 0. ULP program code can use SLEEP instruction to select
* which of the SENS_ULP_CP_SLEEP_CYCx_REG should be used for subsequent wakeups.
*
* However, please note that SLEEP instruction issued (from ULP program) while the system
* is in deep sleep mode does not have effect, and sleep cycle count 0 is used.
*
* For ESP32-s2 the SLEEP instruction not exist. Instead a WAKE instruction will be used.

* @param period_index wakeup period setting number (0 - 4)
