Block Functions
LCD Drive Circuit
The 240-bit LCD drive circuit generates four voltage levels V1, V2, V3, and V4, for driving an LCD panel.
One of the four levels is output to the corresponding Y pin, depending on the combination of the M signal
and the data in latch circuit 2.
Level Shifter
The level shifter changes 5-V signals into high-voltage signals for the LCD drive circuit.
Latch Circuit 2
240-bit latch circuit 2 latches data input from latch circuit 1, and outputs the latched data to the level
shifter, both at the falling edge of each clock 1 (CL1) pulse.
Latch Circuit 1
240-bit latch circuit 1 latches 4-bit or 8-bit parallel data input via the D0 to D7 pins at the timing generated
by the shift register.
Shift Register
The 60-bit shift register generates and outputs data latch signals for latch circuit 1 at the falling edge of
each clock 2 (CL2) pulse.
Data Shifter
The data shifter shifts the destinations of display data output, when necessary.
