Operation Timing
(1) 4-bit capture mode (1 line, 640 dots)
BS = GND (4-bit capture mode)
During the data standby state when the data capture operation enable signal is low (SHL = GND: EIO1),
the next data capture clock (CL2) cancels the standby state. The 4-bit data is captured at the fall of CL2.
When 316 bits are captured, the enable signal becomes the GND level (SHL = GND: EIO2). When 320
bits are captured, the operation automatically stops (the standby state is entered). The second IC is then
activated when pin EIO2 is connected to pin EIO1 of the second IC.
Data output changes at the fall of CL1.
During SHL = GND, captured data d1 and d320 are output to Y1 and Y320, respectively. During SHL =
Vcc, data d1 and d320 are output to Y320 and Y1, respectively.
