STE2004S
Instruction set
51/79
5.2
P
ower down (PD = 1)
At power down, all LCD outputs are kept at V
SS
(display off). Bias generator and V
LCD
generator are off (V
LCDOUT
output is discharged to V
SS
, and then V
LCDOUT
can be
disconnected). The internal oscillator is in off state. An external clock can be provided. The
RAM contents is not cleared.
5.3
Memory blanking procedure
This instruction fills the memory with "blank" patterns, in order to delete patterns randomly
generated in memory when starting up the device. It substitutes (102X8) single "write"
instructions. The procedure can only be programmed if:
PD bit = 0
No instruction can be programmed for a period equivalent to 102X8 internal write cycles
(102X8X1/fclock). The start of the memory blanking procedure is between one and two
fclock cycles from the last active edge (E falling edge for the parallel interface, last SCLK
rising edge for the serial and SPI interfaces, last SCL rising edge for the I
2
C interface).
5.4
Checker board procedure
This instruction fills the memory with "checker-board" pattern, allowing developers to create
a complex module test configuration using one instruction. It can only be programmed if:
PD bit = 0
No instruction can be programmed for a period equivalent to 102X8 internal write cycles
(102X8X1/fclock). The start of checker-board procedure is between one and two fclock
cycles from the last active edge (E falling edge for the parallel interface, last SCLK rising
edge for the serial and SPI interfaces, last SCL rising edge for the I
2
C interface).
5.5
Scrolling function
The STE2004S can scroll the graphics display in units of raster-rows. The scrolling function
changes the correspondence between the rows of the logical memory map and the output
row drivers. The scroll function does not affect the data ram contentm it is only related to the
visualization process. The information output on the drivers is related to the row reading
sequence (the 1st row read is output on R0, the 2nd on R1 and so on). Scrolling means
reading the matrix starting from a row that is sequentially increased or decreased. After
every scrolling command the offset between the memory address and the memory scanning
pointer is increased or decreased by one. The offset range changes in accordance with
MUX Rate. After 64th/65th scrolling commands in MUX 65 mode, or after the 48th/49th
scrolling commands in MUX 49 mode, or after 32nd/33rd scrolling command in MUX 33
mode, the offset between the memory address and the memory scanning pointer is again
zero (Cyclic Scrolling).
A Reset Scrolling Pointer instruction can be executed to force the offset between the
memory address and the memory scanning pointer to zero.
If ICON MODE =1, the Icon Row is not scrolled. If ICON MODE=0 the last row is like a
general purpose row and it is scrolled as other lines.
