STM32F446REの割り込みベクタのメモ

Once the boot pins are selected, the application software can modify the memory accessible in the code area (in this way the code can be executed through the ICode bus in place of the System bus). This modification is performed by programming the Section 8.2.1: SYSCFG memory remap register (SYSCFG_MEMRMP) in the SYSCFG controller.

Address	Boot/Remap in main Flash memory	Boot/Remap in embedded SRAM	Boot/Remap in System memory	Remap in FMC
0x0000 0000 - 0x001F FFFF	Flash (512 KB) Aliased	SRAM1 (112 KB) Aliased	System memory (30 KB) Aliased	FMC bak 1 NOR/PSRAM 1 (128 MB Aliased) or FMC SDRAM bak 1 (128 MB Aliased)

On system reset, the vector table is fixed at address 0x00000000. Privileged software can write to the VTOR to relocate the vector table start address to a different memory location, in the range 0x00000080 to 0x3FFFFF80. For further infomation see Vector table offset register (VTOR) on page 227.

Bits 31:30 Resurved, Bits 29:9 It contains bits [29:9] of the offset of the table base from memory address 0x00000000. Bit 29 determines whether the vector table is in the code or SRAM memory region. Bits 8:0 Reserved,
