*
* Behavior of @enable_sleep >= 1 depends on MCU.
*
* For STM32F103, it's like following.
* 1: Sleep (CPU clock OFF only)
* 2: Stop Wakeup by EXTI (voltage regulator on)
* 3: Stop Wakeup by EXTI (voltage regulator low-power)
* 4: Standby Wakeup by RESET (voltage regulator off)
* For STM32F103, 1 for Sleep (CPU clock OFF only), 2 for Stop (Wakeup
* by EXTI, voltage regulator on), 3 for Stop (Wakeup by EXTI, voltage
* regulator low-power), 4 for Standby (Wakeup by RESET, voltage
* regulator off), and 128 is or-ed to ask WFE instead of WFI.
*
* Return previous value of @enable_sleep.
