H ······ Normal, L ······ Stops the oscillation of the clock
H ······ Normal (T6963CFG has internal pull−up resistor)
L ······ Initialize T6963CFG. Text and graphic have addresses and text and graphic area settings are
Control pin for external DC / DC. DSPON is L when HALT is L or RESET is L.
(When DSPON goes H, the column drivers are cleared.)
H ······ Single−Scan
L ······ Dual−Scan
H ······ Sending data by odd / even separation
L ······ Sending data by simple serial method
LOD at DUAL = L Serial data output for odd columns in lower area of LCD
LSCP at DUAL = L Shift clock pulse output for column drivers in lower area of LCD
Chip enable pin for display memory of any address
Data I / O pins for display memory
Address outputs for display memory
(ad15 = L: for upper area of LCD, ad15 = H: for lower area of LCD)
Read / Write signal for display memory
Data output for odd columns in upper area of LCD
Synchronous signal for row driver
Shift clock pulse for column driver of upper area of LCD
Latch pulse for column driver. Shift clock pulse for row driver
