according to the factor respectively. See “Resizing function”.
RCH[1:0] Sets the number of remainder pixels in horizontal direction when resizing a picture.
By specifying the number of remainder pixels by RCH bits, the data can be transferred without
taking the reminder pixels into consideration. Make sure that RCH = 2’h0 when not using the
resizing function (RSZ = 2’h0) or there are no remainder pixels.
RCV[1:0] Sets the number of remainder pixels in vertical direction when resizing a picture.
By specifying the number of remainder pixels by RCV bits, the data can be transferred without
taking the reminder pixels into consideration. Make sure that RCV = 2’h0 when not using the
resizing function (RSZ = 2’h0) or there are no remainder pixels.

D[1:0] Set D[1:0]=”11” to turn on the display panel, and D[1:0]=”00” to turn off the display panel.
A graphics display is turned on the panel when writing D1 = “1”, and is turned off when writing
D1 = “0”.
When writing D1 = “0”, the graphics display data is retained in the internal GRAM and the
ILI9325 displays the data when writing D1 = “1”. When D1 = “0”, i.e. while no display is shown on the
panel, all source outputs becomes the GND level to reduce charging/discharging current, which is
generated within the LCD while driving liquid crystal with AC voltage.
When the display is turned off by setting D[1:0] = “01”, the ILI9325 continues internal display
operation. When the display is turned off by setting D[1:0] = “00”, the ILI9325 internal display
operation is halted completely. In combination with the GON, DTE setting, the D[1:0] setting controls
display ON/OFF.
