Technical Manual
8.2. System Control Commands
8.2.1. SYSTEM SET
Initializes the device, sets the window sizes, and selects
the LCD interface format. Since this command sets the
basic operating parameters of the S1D13305 series, an
incorrect SYSTEM SET command may cause other
commands to operate incorrectly.
8.2.1.1. C
This control byte performs the following:
1. Resets the internal timing generator
2. Disables the display
3. Cancels sleep mode
Parameters following P1 are not needed if only can-
celing sleep mode.
8.2.1.2. M0
Selects the internal or external character generator ROM.
The internal character generator ROM contains 160, 5
×
7 pixel characters, as shown in figure 70. These charac-
ters are fixed at fabrication by the metallization mask.
The external character generator ROM, on the other
hand, can contain up to 256 user-defined characters.
M0 = 0: Internal CG ROM
M0 = 1: External CG ROM
Note that if the CG ROM address space overlaps the
display memory address space, that portion of the display
memory cannot be written to.
8.2.1.3. M1
Selects the memory configuration for user-definable char-
acters. The CG RAM codes select one of the 64 codes
shown in figure 46.
M1 = 0: No D6 correction.
The CG RAM1 and CG RAM2 address spaces are not
contiguous, the CG RAM1 address space is treated as
character generator RAM, and the CG RAM2 address
space is treated as character generator ROM.
M1 = 1: D6 correction.
The CG RAM1 and CG RAM2 address spaces are
contiguout and are both treated as character generator
RAM.
