4893 * Calls target_read_memory or target_read_phys_memory depending on
4894 * the presence of the "phys" argument
4895 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4896 * to int representation in base16.
4897 * Also outputs read data in a human readable form using command_print
4899 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4900 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4901 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4902 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4903 * on success, with [<count>] number of elements.
4905 * In case of little endian target:
4906 * Example1: "mdw 0x00000000" returns "10123456"
4907 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4908 * Example3: "mdb 0x00000000" returns "56"
4909 * Example4: "mdh 0x00000000 2" returns "3456 1012"
4910 * Example5: "mdb 0x00000000 3" returns "56 34 12"
