6.9 LCD Controller/Driver
The
μ
PD753108 incorporates a display controller which generates segment and common signals according to
the display data memory contents and incorporates segment and common drivers which can drive the LCD panel
directly.
The
μ
PD753108 LCD controller/driver has the following functions:
Display data memory is read automatically by DMA operation and segment and common signals are
generated.
Display mode can be selected from among the following five:
<1> Static
<2> 1/2 duty (time multiplexing by 2), 1/2 bias
<3> 1/3 duty (time multiplexing by 3), 1/2 bias
<4> 1/3 duty (time multiplexing by 3), 1/3 bias
<5> 1/4 duty (time multiplexing by 4), 1/3 bias
A frame frequency can be selected from among four in each display mode.
A maximum of 24 segment signal output pins (S0 to S23) and four common signal output pins (COM0 to
COM3).
The segment signal output pins (S0 to S23) can be changed to the I/O ports (PORT8 and PORT9).
Split resistor can be incorporated to supply LCD drive power (mask option).
Various bias methods and LCD drive voltages are applicable.
When display is off, current flowing through the split resistor is cut.
Display data memory not used for display can be used for normal data memory.
It can also operate by using the subsystem clock.
