→TWL_FIRM
For shutting down the system, TWL_FIRM writes u8 value 8 to [[I2C]] MCU register 0x20. For returning to 3DS-mode, TWL_FIRM writes value 4 to that MCU register to trigger a hardware system reboot.

The TWL_FIRM ARM11-process includes a TWL bootloader, see [http://dsibrew.org/wiki/Bootloader here] and [[Memory_layout#Detailed_TWL_FIRM_ARM11_Memory|here]] for details. See [http://dsibrew.org/wiki/Bootloader here] regarding the RSA code used by TWL_FIRM for all TWL RSA sig-checks.

TWL_FIRM verifies all TWL RSA padding with the following. This is different from the DSi "BIOS" code.
