Note
The SCROLL command is used to configure the display start addresses for the various
screen blocks when indirect addressing is used. The values from REG[0Bh] through
REG[14h] are passed as parameters when the SCROLL command is issued. For further
information on the SCROLL command, see Section 11.1.4, “SCROLL” on page 73.
Screen Block 1 Start Address (SAD1) bits [15:0]
These bits determine the memory start address of screen block 1.
Screen Block 1 Size (SL1) bits [7:0]
These bits determine the size of screen block 1, in lines.
When the start address is changed, the LSB must be programmed before the MSB. The
start address does not change until the MSB is written.
The relationship between the screen block start address (SADx), screen block size
(SLx), and the display mode is described in Table 10-7 “Display Modes,” on page 58.
REG[0Dh] bits 7-0 = screen block 1 size in number of lines - 1
