• Manufacturer Part Number: SSD2119
• Description: 320 Rgb X 240 Tft Lcd Driver Integrated Power Circuit, Source And Gate Driver And Ram
• Manufacturer: Crystalfontz America, Inc.,

ID[1:0]: The address counter is automatically incremented by 1, after data are written to the GDDRAM when ID[1:0] =
“1”. The address counter is automatically decremented by 1, after data are written to the GDDRAM when ID[1:0] = “0”.
The setting of incrementing or decrementing of the address counter can be made independently in each upper and lower
bit of the address. The direction of the address when data are written to the GDDRAM is set with AM bits.
AM: Set the direction in which the address counter is updated automatically after data are written to the GDDRAM.
When AM = “0”, the address counter is updated in the horizontal direction. When AM = “1”, the address counter is
updated in the vertical direction. When window addresses are selected, data are written to the GDDRAM area specified
by the window addresses in the manner specified with ID1-0 and AM bits.
Note: ID and AM functions are not supported in RGB mode

INVDOT: sets the signal polarity of DOTCLK pin. When INVDOT = 0, data is latched at positive edge of DOTCLK.
When INVDOT = 1, data is latched at negative edge of DOTCLK.
INVDEN: sets the signal polarity of DEN pin. When INVDEN = 0, DEN is active high. When INVDEN = 1, DEN is
active low.
INVHS: sets the signal polarity of HSYNC pin. When INVHS = 0, HSYNC is active low. When INVHS = 1, HSYNC is
active high.
INVVS: sets the signal polarity of VSYNC pin. When INVVS = 0, VSYNC is active low. When INVVS = 1, VSYNC is
active high.
