* Note 1: Gamma parameter registers are backuped and restored. But we won't start a fade automatically after wake-up.
* Instead, we will only start a PWM with a constant duty cycle, the same value as before entering the sleep.
* Instead, we will only start a PWM with a fixed duty cycle, the same value as before entering the sleep.

* Note 3: Gamma RAM registers R/W relies both APB and function clock, therefore, retention requires the existence of function clock
