Figure 12 Compared Result for Correction Circuit
The correction circuit compares the present output data (latch circuit (2)) and the next output data (latch
circuit (1)). Depending on the compared result, the circuit resets the high width of CC3 to the VM for the
output without a data change if the data is the non-selected output ((c) in figure 12). The circuit resets the
high width of CC4 to the VM if the data is the selected output ((d) in figure 12). CC3 and CC4 are input
after the last valid data is transferred. CC1 forcibly resets the V1 output to VM for the high width ((a) in
figure 12). CC2 forcibly resets the V0 output to VM for the high width ((b) in figure 12). Therefore,
shadowing caused by waveform distortion is corrected with CC3 or CC4 (non-selected or selected), and
shadowing caused by crosstalk is corrected with CC1 or CC2 (in the V0 or V1 direction).
Note: The high period from CC1 to CC4 should be matched with the shadowing level.
