DESCRIPTION 1) becomes low by (, ) timing. 2) When IG data is input to, the device becomes select mode and reads input data at falling timing. Synchronized at the fall of. Input data is shifted. 3) After reading 80 input data(equivalent to 80 clock cycle in the serial mode or 20 clock cycles in the 4 bit parallel,mode), automatically becomes IG level and data reading is complete. is reset 1.5 cycles later. 4) When two or more devices are used in the chip select mode, of each state is connected to of the next state. (1) of all device connected is reset and device becomes nonselect state and waits for input after the previous 1). (2) When IG level is input to the first in the cascade connection, the first device performs the operation in 2) and 3). (3) When of the second device is connected to of the first device, the second device perform the operations 2) and 3) after the first device.
