Preliminary
LCD driver
The LCD driver can directly drive an LCD panel with 1/8
duty and 1/4 bias. The frame of this LCD driver is fixed
for 64Hz.
LCD driver uses the voltage of the VLCD pin as the
power source. To adjust the view angle, the programmer
can select the real LCD power by the flags VCON0 and
VCON1.TheflagLCDONisusedtoturnOn/OfftheLCD
display. Note that the VLCD voltage must equal or be
less than VDD.
Segment/Common to I/O selection
For the flexible purpose, some of the LCD SEGMENT
pins are shared with the input/output port.
HT95L100/10P provides 4 pins to be selected to SEG-
MENT output pins or I/O pins.
LCD display memory
The phone controller provides an area on embedded
data memory for LCD display. The LCD display memory
are located at bank 1BH and can be read and written to,
only by indirect addressing mode using MP1. When
data is written into the display data area it is automati-
cally read by the LCD driver which then generates the
corresponding LCD driving signals, to turn the display
On or Off, a 1 or 0 is written to the corresponding bit
of the display memory, respectively. All of the LCD dis-
play memories are with random values after the power
on reset and unchanged after other reset conditions.
