T6963C (XL166A00) CPU (LCD Controller)
"H" : Normal
"L" : Clock oscillation stopped (Home
address and data of area digit number are
preserved.)
"H" : Normal (with built-in pull-up resistor)
"L" : T6963C initialized (Home address and
data of area digit number are preserved.)
Data input terminal with CPU I/F (D7 is MSB)
Write signal terminal. Data written into
T6963 when at "L".
Read signal terminal. Data read from
T6963C when at "L".
Chip enable terminal of T6963C. Set to "L" when
transmitting and receiving data with CPU I/F.
/WR = "L" : C/D = "H" : Command WRITE
C/D = "L" : Data WRITE
/RD = "L" : C/D = "H" : Status READ
C/D = "L" : Data READ
Data input/output terminal to/from display
memory ("H" -> ON data, "L" -> OFF data)
Power 5.0V
Data input/output terminal to/from display
memory ("H" -> ON data, "L" -> OFF data)
Read/write signal output terminal to display
memory ("H" -> Read, "L" -> Write)
Display memory chip enable terminal (All
address area)
Address output terminal to display memory
(ad15 = "L" -> Top face, ad15 = "H" ->
Bottom face)
When driving secondary face of LCD2
(DUAL = "L") : Top face and bottom face
switched at ad15.
/ce0 when /DUAL = "H" Display memory chip
enable terminal for addresses 0000 ~ 07FFH.
LSCP when /DUAL = "L" Serial data output terminal
for odd number segments of bottom face LCD.
/ce1 when /DUAL = "H" Display memory chip
enable terminal for addresses 0800 ~ 0FFFH.
LSCP when /DUAL = "L" Shift clock pulse
output terminal for X driver of bottom face LCD.
Serial data output terminal for odd number
segment of top face LCD
Serial data output terminal for even number
segment of top/bottom face LCD when
/SDSEL = "H".
Serial data output terminal for segments of
top/bottom face LCD when /SDSEL = "L".
Shift lock pulse for X driver of top face LCD
Latch pulse for X driver / Shift lock pulse for
Y driver
Synchronous signal for Y driver
Frame signal terminal
Output terminal for checking (Don't care)
Control terminal of external DC/DC. DSPON
= "L" when /HALT, /RESET become
"L". (X driver is cleared when "L" -> "H".)
Power 5.0V
Power supply 0V
Test input terminal. Should be normally
kept open.
