The DIG:DATAn[:type]BITm? command returns the programmed stateof the data line.– The value returned is not affected by the programmed data line polarity. A1 returned always indicates a TTL High level on the data line.– For 16-bit operations using :WORD, n must be 0, 2, 4, 6, 8, or 10.– For 32-bit operations using :LWORd, n must be 0, 4, or 8.– For 64-bit or 96-bit operations using :LW64 or :LW96, n must be 0.– The keyword LW32 maybe used instead of LWORd.– :DATAn and :BITm are the keywords used to write data to port n and bit m.The port number n and bit number m must be the last character of thekeyword without spaces.Parameter Name Parameter Type Range of Values DefaultDATAn Numeric BYTE none, 0 through 11WORD none, 0, 2, 4, 6, 8, or 10LWORd none, 0, 4, or 8LW64 none or 0LW96 none or 00BITm Numeric BYTE 0 - 7WORD 0 - 15LWORd 0 - 31LW64 0-63LW96 0-95None
