+/* The STM32F407ZET6 has 512Kb of FLASH beginning at address 0x0800:0000 and

+ *
+ * 1) 112Kb of SRAM beginning at address 0x2000:0000
+ * 2)  16Kb of SRAM beginning at address 0x2001:c000
+ * 3)  64Kb of SRAM beginning at address 0x2002:0000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
