This section presents two examples to show how to initialize the S1D13503 registers and write a pixel to the display. Code
to initialize the S1D13503 is provided in Section 7.2, “Initialization Code” on page 60.
The following examples describe values written to registers.

Example 1:
Program S1D13503 Registers in the following order with the data supplied:
A “panel specific” value is one required for the given type of panel. Such a value must never change after initializa-
tion of all registers.
An “implementation specific” value is one required for the hardware implementation of the S1D13503. Such a value
must never change after initialization of all registers. Refer to the S1D13503 Hardware Functional Specification and
S5U13503B00C Evaluation Board User’s Manual for more information on hardware implementation issues.
An “application specific” value is one that can be changed by the program after initialization of all registers.
(in Binary)
Data
Initialize the registers for a 256 color 320 x 240 single panel LCD with 128k of display
memory. Afterwards write one pixel to the top left corner of the display.

procedure is to turn this bit off during register initialization and

supply design (for S5U13503B00C, set bit to 0 to disable power
supply) (application specific; the recommended procedure is to
disable the power supply during register initialization and
afterwards enable the power supply)
(panel specific)
operation set to 00b)
(implementation and panel specific)
(panel specific)
bits 7 and 6 must be zero
b7 = display off (application specific; the recommended
b6 = single panel (panel specific)
b5 = XSCL is masked (panel specific)
b4 = LCDE = LCDENB pin = set to disable specific power
b3 = N/A for 256 colors (application specific)
b2 = 4 bit LCD data width when combined with AUX[03] bit 3
b1 = 16 bit Memory Interface (implementation specific)
b0 = RAMS ignored (implementation specific)
bits 7-0 = bits 7-0 of Line Byte Count
bit 8 of Line Byte Count is bit 0 of AUX[03h]
bits 7-6 = Power Save Mode 0 (application specific - for normal
bit 5 = LCD interface signals forced low during Power Save
bit 4 = no LUT bypass (application specific)
bit 3 = 4 bit LCD data width when combined with AUX[01] bit 2
bit 2 = 256 color mode (application specific)
bit 1 = color panel attached (panel specific)
bit 0 = bit 8 of Line Byte Count (panel specific, see AUX[02h])
bits 7-0 = bits 7-0 of Total Display Line Count
bits 9-8 of Total Display Line Count in bits 1-0 of AUX[05h]
