4413 * mdh [phys] <address> [<count>] - for 16 bit reads
4414 * mdb [phys] <address> [<count>] - for 8 bit reads

4418 * Calls target_read_memory or target_read_phys_memory depending on
4419 * the presence of the "phys" argument
4420 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4421 * to int representation in base16.
4422 * Also outputs read data in a human readable form using command_print
4423 *
4424 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4425 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4426 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4427 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4428 * on success, with [<count>] number of elements.
4429 *
4430 * In case of little endian target:
4431 * Example1: "mdw 0x00000000" returns "10123456"
4432 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4433 * Example3: "mdb 0x00000000" returns "56"
4434 * Example4: "mdh 0x00000000 2" returns "3456 1012"
