STM32L152R6T6A

h2. Design guides

* 100nF on NRST
* VDD: n x 100 nF + 1 x 4.7 μF
* VDA: 10 nF + 1 μF
* BOOT: 10K to ground
* NRST: 10K to VDD an STM32 examples

h2. Low power modes

SLEEP MODE: CPU CLK is turned OFF; no effect on other clocks or analog clock sources. The current consumption is HIGHEST in this mode, compared to other Low Power Modes
* Use HAL_PWR_EnableSleepOnExit() to automatically go to sleep again when an ISR has finished
