Determine the display memory location for the first half of the image.
For simplicity, assign the beginning of display memory as the starting address of the image’s first half (see
Figure 19). For the S5U13503B00C, this address is D000:0000h, bank 0.
Program the Screen 1 Display Start Address Register to point to the beginning of the first half of the image.
Since the first half is at the beginning of display memory, program the Screen 1 Display Start Address Register to
0000h.
AUX[06h] = 00h
AUX[07h] = 00h
Determine the size of the image’s first half.
Determine the display memory location for the second half of the image.
Place the second half of the image immediately after the first half (see Figure 19). Assign the starting address for the
second half as follows:
Note that if the address of the second half of the image is larger than D000:FFFFh, then switch to bank 1, reset the
segment to D000h, and keep the offset. For example, if the address of the second half of the image were
{D001:9200h, bank 0}, then this address must be changed to {D000:9200h, bank 1}.
