592 * by overwriting data with a breakpoint instruction. On the other

4712 * Count defaults to 1.
4714 * Calls target_read_memory or target_read_phys_memory depending on
4715 * the presence of the "phys" argument
4716 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4717 * to int representation in base16.
4718 * Also outputs read data in a human readable form using command_print
4720 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4721 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4722 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4723 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4724 * on success, with [<count>] number of elements.
4726 * In case of little endian target:
4727 * Example1: "mdw 0x00000000" returns "10123456"
4728 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4729 * Example3: "mdb 0x00000000" returns "56"
4730 * Example4: "mdh 0x00000000 2" returns "3456 1012"
