Display memory
LCD display
The LCD display memory is embedded in the
data memory (mapped to the addresses
C0H~E 2H of bank 27). It can be read and writ-
ten to as a normal data memory. The following
figure illustrates the mapping between the dis-
play memory and the LCD pattern.
To turn the display on/off, the programmer
writes 1 or 0 to the corresponding bit of the
display memory. The LCD display module can
be of any form as long as the number of the
common doesn’t exceed 4 and the number of the
segment is not over 35.
The entire number of the LCD driver output is
35
×
4. The LCD driver can directly drive an LCD
of 1/4 duty cycle and 1/3 bias. All of the LCD
segments are random at the initial clear mode.
The frequency of the LCD driving clock is fixed
at about 256Hz, and cannot be changed. It is set
by HOLTE K according to the application.
The following is an example of an 8-segment
digit display, which shows a waveform of “5”.
Pager decoder
The pager decoder is a POCSAG code pager
decoder at 512, 1200, or 2400 bps data rate,
compatible with CCIR radio paging Code No.1
(POCSAG Code). The decoder supports six user
addresses and six independently programma-
ble user frames.
