4904 * mdh [phys] <address> [<count>] - for 16 bit reads
4905 * mdb [phys] <address> [<count>] - for 8 bit reads
4906 *
4907 * Count defaults to 1.
4908 *
4909 * Calls target_read_memory or target_read_phys_memory depending on
4910 * the presence of the "phys" argument
4911 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4912 * to int representation in base16.
4913 * Also outputs read data in a human readable form using command_print
4914 *
4915 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4916 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4917 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4918 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4919 * on success, with [<count>] number of elements.
4920 *
4921 * In case of little endian target:
4922 * Example1: "mdw 0x00000000" returns "10123456"
4923 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4924 * Example3: "mdb 0x00000000" returns "56"
4925 * Example4: "mdh 0x00000000 2" returns "3456 1012"
