3.2.1.1 – 3.2.1.5
3.2.1.1 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.
3.0 Command Description
as character generator RAM, and the CG RAM2
address space is treated as character generator ROM.
M1 = 1: 64 char CG RAM + CG RAM2
The CG RAM1 and CG RAM2 address spaces are
contiguous and are both treated as character genera-
tor RAM.
3.2.1.2 M0
Selects the internal or external character generator
ROM. The internal character generator ROM con-
tains 160, 5 × 7 pixel characters. These characters are
fixed at fabrication by the metalization mask. The
external character generator ROM can contain up to
256 user-defined characters.
M0 = 0: Internal CG ROM
M0 = 1: External CG ROM
3.2.1.4 M2
Selects the height of the character defined in external
CG ROM and CG RAM. Characters more than 16 pix-
els high can be displayed by creating a bitmap for
each portion of each character and using the
SED1330F/1335F/1336F’s graphics mode to reposi-
tion them.
M2 = 0: 8-pixel character height (2716 or
equivalent ROM)
M2 = 1: 16-pixel character height (2732
or equivalent 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.
3.2.1.3 M1
Selects the CG RAM area for user-definable charac-
ters. The CG RAM codes are selected from the 64
codes shown in Figure 59.
M1 = 0: CG RAM1; 32 char
3.2.1.5 W/S
Selects the LCD drive method.
W/S = 0: Single-panel drive
W/S = 1: Dual-panel drive
The CG RAM1 and CG RAM2 address spaces are not
contiguous, the CG RAM1 address space is treated
