9.2.8 SYSCFG register maps for
STM32F405xx/07xx and STM32F415xx/17xx
The following table gives the SYSCFG register map and the reset values.
Refer to Section 2.3: Memory map for the register boundary addresses.
9.3 SYSCFG registers for STM32F42xxx and STM32F43xxx
9.3.1 SYSCFG memory remap register (SYSCFG_MEMRMP)
This register is used for specific configurations on memory remap:
• Three bits are used to configure the type of memory accessible at address
0x0000 0000. These bits are used to select the physical remap by software and so,
bypass the BOOT pins.
• After reset these bits take the value selected by the BOOT pins. When booting from
main Flash memory with BOOT pins set to 10 [(BOOT1,BOOT0) = (1,0)] this register
takes the value 0x00.
• Other bits are used to swap FMC SDRAM Bank 1/2 with FMC Bank 3/4 and configure
the Flash Bank 1/2 mapping
