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