576 * of the address parameter
577 * @param address Optionally used as the program counter.
578 * @param handle_breakpoints True iff breakpoints at the resumption PC
579 * should be skipped. (For example, maybe execution was stopped by
580 * such a breakpoint, in which case it would be counterprodutive to
582 * @param debug_execution False if all working areas allocated by OpenOCD
583 * should be released and/or restored to their original contents.
584 * (This would for example be true to run some downloaded "helper"
585 * algorithm code, which resides in one such working buffer and uses
586 * another for data storage.)
588 * @todo Resolve the ambiguity about what the "debug_execution" flag
589 * signifies. For example, Target implementations don't agree on how
590 * it relates to invalidation of the register cache, or to whether
591 * breakpoints and watchpoints should be enabled. (It would seem wrong
592 * to enable breakpoints when running downloaded "helper" algorithms
593 * (debug_execution true), since the breakpoints would be set to match
594 * target firmware being debugged, not the helper algorithm.... and
595 * enabling them could cause such helpers to malfunction (for example,
596 * by overwriting data with a breakpoint instruction. On the other
597 * hand the infrastructure for running such helpers might use this
598 * procedure but rely on hardware breakpoint to detect termination.)

4744 * Calls target_read_memory or target_read_phys_memory depending on

4746 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4747 * to int representation in base16.
4748 * Also outputs read data in a human readable form using command_print
4750 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4751 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4752 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4753 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4754 * on success, with [<count>] number of elements.
4756 * In case of little endian target:
4757 * Example1: "mdw 0x00000000" returns "10123456"
4758 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4759 * Example3: "mdb 0x00000000" returns "56"
4760 * Example4: "mdh 0x00000000 2" returns "3456 1012"
