The mode and marker memories store 66 nine-bit words that define the operation of the part and contain marker information. The REGADR input is used to select the proper register. Data is written over the CI bus and read on the DO bus. The AT pin controls whether data is a mode word or a marker. When AT is low, the data written is mode information, which is stored in the mode registers contained in the controller block. When AT is high, the data is a marker, and is stored in the marker memory. To prevent erroneous operation STARTIOn should be high, and IODV and DV should be low during initialization.
