Note
The initialization example shown below is for a S1D13700F02 with an 8-bit micropro-
cessor interface bus and an Epson EG4810S-AR display unit (512 × 128 pixels).
Set the cursor address to the start of each screen’s layer memory, and use MWRITE to
fill the memory with space characters, 20h (text screen only) or 00h (graphics screen
only). Determining which memory to clear is explained in Section 15.1.3, “Display
Mode Setting Example 1: Combining Text and Graphics” on page 109.
Table 15-2 Indirect Addressing Initialization Procedure
M0: Internal CGROM (REG[00h] bit 0)
M2: 8 lines per character (REG[00h] bit 2)
W/S: Two-panel drive (REG[00h] bit 3)
IV: Sets top-line compensation to none (REG[00h] bit 5)
FX: Horizontal character size = 8 pixels (REG[01h] bits 3-0)
MOD: Two-frame AC drive (REG[01h] bit 7)
