Internal operationsare base on the clocks which are frequency divided according to the value of DIV1-0.Frame frequency can be adjusted along with the 1H period (RTN[3:0]). When thedrive line count is changed, the frame frequency must be also adjusted.fosc = R-C oscillation frequencyDIV1 DIV0 Division Ratio Internal Operation Clock Frequency0 0 1 fosc / 10 1 2 fosc / 21 0 4 fosc / 41 1 8 fosc / 8Formula for the Frame Frequency:Frame frequency = fosc/( RTN × DIV × (NL+BP+FP) ) [HZ]fosc: RC oscillation frequencyHimax ConfidentialThis information contained herein is the exclusive property of Himax and shall not be distributed, reproduced, or disclosedin whole or in part without prior written permission of Himax.-P.107-July, 2007
