W925E/C625
8-bit CID Microcontroller
An internal voltage pump is enable/disable by option code. The LCD on/off is controlled by bit
LCDON (SCON1.6). If the voltage pump is enable, when LCDON is high to pump voltage and the
LCD waveform is output to LCD pins according the LCD memory, when LCDON is low to turn off
the voltage pump. The voltage of internal regulator is the base voltage of the voltage pump which
5 times
of the base voltage. The output voltage of the regulator is tunable by 4 bits in regulator
voltage control register (REGVC). When REGVC is equal to 0AH, the output voltage is 1.0V. The
higher value of REGVC the lower voltage output of regulator. The adjustable voltage range is
about from 0.72V to 1.48V . Accordingly, the LCD contrast is controlled by the value of REGVC.
The variation of the voltage depends on the V
DD
. Following is the table of REGVC vs regulator
voltage.

LCD Frequency
The alternating frequency of the LCD can be set as 16Hz, 32Hz, 64Hz and 128Hz that are
determined by 2 bits of option code. structure of the LCD alternating frequency (F
LCD
) is shown in
Figure 6-14.
