CHAPTER 24 LCD CONTROLLER
power supply.
●
LCDC enable registers 1 to 5 (LCDCE1 to 5)
These registers are used to control port inputs, blink interval, and pins.
●
LCDC blinking setting registers 1, 2 (LCDCB1/2)
These registers are used to turn blinking on or off & operate in product with dual clock system.
in the product with single clock system, this function is disabled, the LCDCB1/2 has no effec
●
Display RAM
28 x 4 bits of RAM for generating segment output signals. The contents of this RAM are read
automatically in synchronization with the common signal selection timing and output from the
segment output pins.
The contents of VRAM is output from segment output pin when display RAM is re-written.
●
Clock selection
The frame frequency is generated based on the selection from amongst the eight frequencies
generated from the two clocks.
●
Timing control
The common and segment signals are controlled based on the frame frequency and register
settings.
●
AC waveform generator circuit
This block generates AC waveforms for driving the LCD from timing control signals.
●
Common driver
This block is the driver of the LCD common pins.
●
Segment driver
This block is the driver of the LCD segment pins.
●
Divider resistor
This block is a resistor used to generate the LCD drive voltage. The divider resistor can be
connected as an external component when the V1 to V3 pins serve as the divider resistor
connection pins.
■
LCD Controller Power Supply Voltage
The power supply voltage for the LCD driver is generated by using the internal divider resistors or
by connecting divider resistors to the V1 to V3 pins.
■
Input Clock
The LCD controller uses the output clock of timebase timer or watch prescaler as the input clock
(operation clock).
