Start-up procedure Read the status bytes until POR = 0 and send all subaddress bytes. The horizontal output signal is switched-on when the oscillator is calibrated. Each time before the data in the IC is refreshed, the status bytes must be read. If POR = 1, the procedure mentioned above must be carried out to restart the IC. When this procedure is not followed the horizontal frequency may be incorrect after power-up or after a power dip. Valid subaddresses: 00 to 1A (subaddresses 04 to 07 and 17 are not used), subaddress FE is reserved for test purposes.Auto-increment mode available for subaddresses. Table 1 Input status bits.
