4914 * @brief Reads an array of words/halfwords/bytes from target memory starting at specified address.
4916 * Usage: mdw [phys] <address> [<count>] - for 32 bit reads
4917 * mdh [phys] <address> [<count>] - for 16 bit reads
4918 * mdb [phys] <address> [<count>] - for 8 bit reads
4920 * Count defaults to 1.
4922 * Calls target_read_memory or target_read_phys_memory depending on
4923 * the presence of the "phys" argument
4924 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4925 * to int representation in base16.
4926 * Also outputs read data in a human readable form using command_print
4928 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4929 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4930 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4931 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4932 * on success, with [<count>] number of elements.
4934 * In case of little endian target:
4935 * Example1: "mdw 0x00000000" returns "10123456"
4936 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4937 * Example3: "mdb 0x00000000" returns "56"
4938 * Example4: "mdh 0x00000000 2" returns "3456 1012"
4939 * Example5: "mdb 0x00000000 3" returns "56 34 12"
