I_SLEEP_CYCLE_SEL macro

Select the time interval used to run ULP program. This instructions selects which of the SENS_SLEEP_CYCLES_Sx registers' value is used by the ULP program timer. When the ULP program stops at I_HALT instruction, ULP program timer start counting. When the counter reaches the value of the selected SENS_SLEEP_CYCLES_Sx register, ULP program start running again from the start address (passed to the ulp_run function). There are 5 SENS_SLEEP_CYCLES_Sx registers, so 0 <= timer_idx < 5. By default, SENS_SLEEP_CYCLES_S0 register is used by the ULP program timer.
