## Detailed Description

## Macro Definition Documentation

#define CODE_REGION_1_START SD_SIZE_GET(MBR_SIZE)

Size of the Code Region 0, found in the UICR.CLEN0 register.

This value is identical to the start of Code Region 1. This value is used for compilation safety, because the linker will fail if the application expands into the bootloader. At run time, the bootloader uses the value found in UICR.CLEN0.

#define INIT_COMMAND_MAX_SIZE 256

Maximum size of the init command stored in dfu_settings.

#define NRF_DFU_BANK_INVALID 0x00

DFU bank state codes.

The DFU bank state indicates the content of a bank: A valid image of a certain type or an invalid image.Invalid image.

#define NRF_DFU_BANK_VALID_APP 0x01

Valid application.

#define NRF_DFU_BANK_VALID_BL 0xAA

Valid bootloader.

#define NRF_DFU_BANK_VALID_SD 0xA5

Valid SoftDevice.

#define NRF_DFU_BANK_VALID_SD_BL 0xAC

Valid SoftDevice and bootloader.
