23 / 61 page  STE2002 Instruction set 23/61 4.6 Dual partial display If the PE Bit is set to a logic one the dual partial display mode is enabled. Eight partial display modes are 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].). This allows switching from normal mode to partial display mode applying one instruction. The HV generator is automatically re configured 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 PRS[1:0], Vop[6:0], BS[2:0], CP[2:0] values the instruction flow proposed in Fig.46 must be followed. To setup Partial Display Sectors Start Address and Partial Display Mode no particular instruction flow has to be followed. Table 7.
