Trend Trig Bit

p1260 selects the number of data points to store prior to the trend trigger (pre-trigger data). p 1280 or p1281, depending on the data type of the trend data, determines the marker value placed in the trend data at the beginning of the pre-trigger data (trigger point - p1260 - 1). Pre -trigger data is located at negative pointer values ranging from [0 - p1260 - 1] to -1. The trigger point data value is located at pointer value of 0 in p1283. Post -trigger data is located at positive pointer values ranging from 0 to [0 + p1260.
