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