LCD driver data bus:
LD23 to LD0 pins
To be connected to LCD driver data bus.
8-bit mode: LD7 to LD0
TFT mode: LD23 to LD0
LCP0 pin
Data shift clock for TFT source driver Shift clock pulse output pin 0. To be connected to
column driver’s CP pin. The LCD driver latches the
data bus value on the falling edge of this pin.
LHSYNC pin
Vertical shift clock for TFT gate driver Latch pulse output pin. To be connected to the LCD
driver’s LP pin. The display data in the LCD driver’s
output line register is updated on the rising edge of
this pin.
LLOAD pin
