Oscillator
This is on-chip Oscillator with external resistor. Its frequency is controlled by external resistor between OSC1 and
VDD. This oscillator signal is used in the voltage converter and display timing generation circuit.
Display Timing Generator Circuit
This circuit generates some signals to be used for displaying LCD. The display clock, CL(internal), generated by
oscillation clock, generates the clock for the line counter and the signal for the display data latch. The line address of
on-chip RAM is generated in synchronization with the display clock and the display data latch circuit latches the
128-bit display data in synchronization with the display clock. The display data, which is read to the LCD driver, is
completely independent of the access to the display data RAM from the microprocessor. The display clock
generates an LCD AC signal (M) which enables the LCD driver to make a AC drive waveform, and also generates an
internal common timing signal and start signal to the common driver. The frame signal or the line signal changes the
M by setting internal instruction. Driving waveform and internal timing signal are shown in Figure 9.
