... C-bus registers stable between the V-sync pulses, allowing for asynchronous read-out. GENERAL DESCRIPTION The TDA4821P performs the ‘autosize’ feature for colour monitors. The IC measures the timing of active H/V video with respect to the H-sync and V-sync pulses and also with respect to the horizontal flyback pulse in order to allow the microcontroller to adjust the display settings automatically, in particular parameters HSIZE, VSIZE, HPOS and VPOS ...
