Holtek s sound library supports only sound
clock frequencies of 128K or 64K. To use
Holtek s sound library, the proper system clock
andmaskoptionshouldbeselected.
LCDdisplaymemory
As mentioned in the data memory section the
LCD display memory is embedded in the data
memory. It can be read and written to in the
samewayasnormaldatamemory.
The figures show the mapping between the dis-
playmemoryandLCDpatternfortheHT1130.
To turn the display on or off an 1/0 is written to
thecorrespondingbitofthedisplaymemory.
The LCD display module may have any form as
long as the number of commons does not exceed
4 and the number of segments does not exceed
32.
LCDdriveroutput
All LCD segments are random after an initial
clear. The bias voltage circuits of the LCD dis-
play is built-in and no external resistor is
needed.
The output number of the HT1130 LCD driver
is 32
′
4 which can directly drive an LCD with
1/4 (or 1/3 by mask option) duty cycle and 1/3
bias.
The frequency of the LCD driving clock is fixed
at about 256Hz. This is set by Holtek according
totheapplicationandcannotbechanged.
