A frame consists of 280 true columns plus one dummy column of eight pixels. As two pixels are output at a time, a system must send 281 x 4 = 1124 clock pulses to read one frame.Reset must be low when reading the frames. > The clock is taken into account on its falling edge and data is output on its rising edge.For each clock pulse, after the start sequence, a new byte is output on the Do0-3 and De0-3 pins. This byte contains two pixels: 4-bit on Do0-3 (odd pixels), 4-bit on De0-3 (even pixels).To output the data, the output enable (OE) pin must be low. When OE is high, the Do0-3 and De0-3...

Figure 3-11. Nap ModeIn nap mode, all internal transistors are in shut mode. Only leakage current is drained in the power supply, generally less than the tested value. > Nap mode NapClock PCLKReset RST When the clock is stopped (set to 1) and the reset is low (set to 0), the devices analog sections drain some current, whereas, if the outputs are connected to a standard CMOS input, the digital section does not consume any current (no current is drained in the I/O). In this case the typical current value is 5 mA. This current does not depend on the voltage (it is almost the same from 3 to...
