557 * it relates to invalidation of the register cache, or to whether
558 * breakpoints and watchpoints should be enabled. (It would seem wrong
559 * to enable breakpoints when running downloaded "helper" algorithms
560 * (debug_execution true), since the breakpoints would be set to match
561 * target firmware being debugged, not the helper algorithm.... and
562 * enabling them could cause such helpers to malfunction (for example,
563 * by overwriting data with a breakpoint instruction. On the other
564 * hand the infrastructure for running such helpers might use this

4521 * @brief Reads an array of words/halfwords/bytes from target memory starting at specified address.
4523 * Usage: mdw [phys] <address> [<count>] - for 32 bit reads
4524 * mdh [phys] <address> [<count>] - for 16 bit reads
4525 * mdb [phys] <address> [<count>] - for 8 bit reads
4527 * Count defaults to 1.
4529 * Calls target_read_memory or target_read_phys_memory depending on
4530 * the presence of the "phys" argument
4531 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4532 * to int representation in base16.
4533 * Also outputs read data in a human readable form using command_print
4535 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4536 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4537 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4538 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4539 * on success, with [<count>] number of elements.
4541 * In case of little endian target:
4542 * Example1: "mdw 0x00000000" returns "10123456"
4543 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4544 * Example3: "mdb 0x00000000" returns "56"
4545 * Example4: "mdh 0x00000000 2" returns "3456 1012"
4546 * Example5: "mdb 0x00000000 3" returns "56 34 12"
