/** Device specific implementation of the codeplug for the Baofeng DM-1701.
 *
 * The codeplug consists of two segments. The first segment starts at address @c 0x002000 and ends at
 * address @c 0x040000. The second segment starts at address @c 0x110000 and ends at @c 0x1a0000. The
 * segments must align with @c 0x400 (1024 bytes).
 *
 * @section dm1701cpl Codeplug structure within radio
 * The codeplug structure is reverse engineered almost completely and can be programmed from
 * scratch. That is, it is not necessary to update an existing codeplug on the radio.
