Shift-register Type LCD Driver Control
Common (row):
Segment (column): 32, 64, 80, 120, 128,
8 bits, 16 bits selectable
8 bits, 4 bits selectable
250 ns/1 byte at Byte mode
375 ns/1 byte at Nibble mode
Data bus: Connect with DI pin of column driver.
Upper 7 pins do not use in byte mode and
upper 4 pins do not use in nibble mode.
not used
not used
Shift clock pulse: Connect with SCP pin of
column driver. LCD driver latches data bus
value by falling edge of this pin.
Latch pulse output: Connect with LP/EIO1 pin
of column/row driver. Display data is latched in
output buffer in LCD driver by rising edge of
this pin.
LCD frame output: Connect with FR pin of
column/row driver.
Cascade pulse output: Connect with DIO1 pin
of row driver. This pin outputs 1 shot pulse by
every D3BFR pin changes.
Display off output: Connect with /DSPOF terminal of column/row driver.
L means display off and H means display on.

Equal to memory cycle
Data bus: Connect with DB pin of
column/row driver.
Write strobe: Connect with /WR pin of
column/row driver.
Address 0: Connect with D/I pin of
column driver.
When A0 = 1 data bus value means
display data, when A0 = 0 data bus
means instruction data.
