The end of the procedure will be notified ontheBSY_FLG pad going HIGH, while LOW the procedure isrunning.
Any instruction programmed withBSY_FLG LOW will be ignored, that is, no instruction can be programmed for
a period equivalent to 128X9 internal write cycles (128X9X1/fclock). The start of Memory blanking procedure
willbe between one and two fclock cycles from the last active edge (E rising edge for the parallel interface, last
SCLK rising edge for the Serial interface, last SCL rising edge for the I
2
C interface).
Scroll
The STE2001 can scroll the graphics display in units of raster-rows. The scrolling function is achieved changing
the correspondence between the rows of the logical memory map and the output rowdrivers. The scroll function
doesn’t affect the data ram content. 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 is between 0 to 63 in mux 65 mode and 0-31 in mux 33 mode. After the
64th scrolling command in mux 65 mode and after the 32th in mux 33 mode, the offset between the memory
address and the memory scanning pointer is again zero (Cyclic Scrolling). Bank8 is always accessed last in
each frame, and so isn’t scrolled.
If the DIR Bit is set to a logic zero the offset register is increased by one and the raster is scrolled from top down. If
the DIR Bit is set to a logicone the offset register is decreased by one and the raster is scrolled from bottom-up.
Bus Interfaces
To provide the widest flexibility and ease of use the STE2001 features three different methods for interfacing
the host Controller. To select the desired interface the SEL1 and SEL2 pads need to be connected to a logic
LOW (connect to GND) or a logic HIGH (connect to VDD). All the I/O pins of the unused interfaces must be
connected to GND. If I/O pins voltage is lower than VDD interfaces could sink more current than expected.
All interfaces are working while the STE2001 is in Power Down.
I
2
C Interface
The I
2
C interface is a fully complying I
2
C bus specification, selectable to work in both Fast (400kHz Clock) and
High Speed Mode (3.4MHz).
This bus is intended for communication between different Ics. It consists of two lines: one bi-directional for data
signals (SDA) and one for clock signals (SCL). Both the SDA and SCL lines must be connected to a positive
supply voltage via an active or passive pull-up.
The following protocol has been defined:
- Data transfer may be initiated only when the bus is not busy.
- During data transfer, the data linemust remainstable whenever the clock line is high. Changes in the data line
while the clock line is high will be interpreted as control signals.
Accordingly, the following bus conditions have been defined:
BUS not busy:
Both data and clock lines remain High.
StartData Transfer:
A change in the state of the data line, from High to Low, while the clock is High, define the
START condition.
