Instruction set
STE2004S
52/79
If the DIR bit is set to a logic 0, the offset register is increased by one and the raster is
scrolled from top down. If the DIR bit is set to a logic 1, the offset register is decreased by
one and the raster is scrolled from bottom-up.
5.6
Dual partial display
If the PE bit is set to a logic one the dual partial display mode is enabled. There are eight
partial display modes available. The offset of the two partial display zones is row by row
programmable. The icon row is accessed last in each partial display frame.
Two sets of register for the HV-generator parameters are provided (PRS[1:0], Vop[6:0],
BS[2:0], CP[2:0]), allowing normal mode and partial display mode to be switched using one
instruction. The HV generator is automatically reconfigured using the parameters related to
the enabled mode. The parameters of the two sets of registers with the same function are
located in the same position of the instruction set. The registers related to the normal mode
are accessible when normal mode (PE=0) is selected, the others are accessible when the
partial display mode is enabled (PE=1). To setup the PRS[1:0], Vop[6:0], BS[2:0], CP[2:0]
values, follow the instruction flow proposed in
Figure 54. To setup partial display sectors
start qddress and partial display mode no particular instruction flow has to be followed.
