504 * (debug_execution true), since the breakpoints would be set to match
505 * target firmware being debugged, not the helper algorithm.... and
506 * enabling them could cause such helpers to malfunction (for example,
507 * by overwriting data with a breakpoint instruction. On the other
508 * hand the infrastructure for running such helpers might use this
509 * procedure but rely on hardware breakpoint to detect termination.)

4350 * mdh [phys] <address> [<count>] - for 16 bit reads
4351 * mdb [phys] <address> [<count>] - for 8 bit reads
4352 *
4353 * Count defaults to 1.
4354 *
4355 * Calls target_read_memory or target_read_phys_memory depending on
4356 * the presence of the "phys" argument
4357 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4358 * to int representation in base16.
4359 * Also outputs read data in a human readable form using command_print
4360 *
4361 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4362 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4363 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4364 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4365 * on success, with [<count>] number of elements.
4366 *
4367 * In case of little endian target:
4368 * Example1: "mdw 0x00000000" returns "10123456"
4369 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4370 * Example3: "mdb 0x00000000" returns "56"
4371 * Example4: "mdh 0x00000000 2" returns "3456 1012"
4372 * Example5: "mdb 0x00000000 3" returns "56 34 12"
