4517 * @brief Reads an array of words/halfwords/bytes from target memory starting at specified address.
4518 *
4519 * Usage: mdw [phys] <address> [<count>] - for 32 bit reads
4520 * mdh [phys] <address> [<count>] - for 16 bit reads
4521 * mdb [phys] <address> [<count>] - for 8 bit reads
4522 *
4523 * Count defaults to 1.
4524 *
4525 * Calls target_read_memory or target_read_phys_memory depending on
4526 * the presence of the "phys" argument
4527 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4528 * to int representation in base16.
4529 * Also outputs read data in a human readable form using command_print
4530 *
4531 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4532 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4533 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4534 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4535 * on success, with [<count>] number of elements.
4536 *
4537 * In case of little endian target:
4538 * Example1: "mdw 0x00000000" returns "10123456"
4539 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4540 * Example3: "mdb 0x00000000" returns "56"
4541 * Example4: "mdh 0x00000000 2" returns "3456 1012"
4542 * Example5: "mdb 0x00000000 3" returns "56 34 12"
