FUNCTIONAL OPERATIONS OF EACH BLOCK
BLOCK
In case of segment mode, controls the selection or non-selection of the chip.
Following and LP signal input, and after the chip selection signal is input, a
selection signal is generated internally until 160 bits of data have been read in.
Once data input has been completed, a selection signal for cascade connection is
output, and the chip is non-selected. In case of common mode, controls the
input/output data of bi-directional pins.
In case of segment mode, keeps input data which are 2 clocks of XCK at 4-bit
parallel input mode in latch circuit, or keeps input data which are 1 clock of
XCK at 8-bit parallel input mode in latch circuit; after that they are put on the
internal data 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.
In case of segment mode, latches the data on the data bus. The latch state of each
LCD rive output pin is controlled by the control logic and the data latch control;
160 bits of data are read in 20 sets of 8 bits.
In case of segment mode, all 160 bits which have been read into the data latch
are simultaneously latched at the falling edge of the LP signal, and are output to
the level shifter block. In case of common mode, shifts data from the data input
pin at the falling edge of the LP signal.
The logic voltage signal is level-shifted to the LCD drive voltage level, and in
output to the driver block.
Drives the LCD drive output pins from the line latch/shift register data, and
selects one of 4 levels(V

, or V

) based on the S/C, FR and /DISPOFF
signals.
Controls the operation of each block. In case of segment mode, when an LP
signal has been input, all blocks are rest and the control logic waits for the
selection signal output from the active control block. Once the selection signal
has been output, operation of the data latch and data transmission is controlled,
160 bits of data are read in , and the chip in non-selected. In case of common
mode, controls the direction of data shift.
