Function

In case of segment mode, controls the selection or deselection

of the chip.

Following a LP signal input, and after the chip select signal is

input, a select signal is generated internally

until 160 bits of

data have been read in.

Once data input has been completed, a select signal for cascade

connection is output. and the chip is deselected.

In case of common mode, controls the input/output

data of bidi-

rectional pins.

In case of segment mode, keep input data which are 2 clocks of

XCK at 4-bit parallel mode into latch circuit, or keep input

data which are 1 clock of XCK at 8-bit parallel mode into latch

circuit.after

that they are put on the internal data bus 8 bits

at a time.

In case of segment mode, selects the state of the data latch

which reads in the data bus signals. The shift direction is

controlled by the control logic, for every 16 bits of data read

in, the selection signal shifts one bit based on the state of

the control circuit.
