ERTICAL SCROLLING DEFINITION
In the PCF8833 three different scrolling modes can be used. These scrolling modes differ from each other in the way the
RAM to display mapping is done. The vertical scrolling is defined as follows:
Vertical scrolling definition (VSCRDEF) command
TF[7:0] defines the number of lines for the top fixed area on the display, there is no top fixed area when TF[7:0] = 0
SA[7:0] defines the number of lines for the scrolling area on the display
BF[7:0] defines the number of lines for the bottom fixed area on the display, there is no bottom fixed area when
BF[7:0] = 0.
Figure 12 illustrates the 4 scrolling configurations that can be defined.
Table 34
Vertical scrolling definition register bits
There are 3 different scrolling modes, which are selected as follows:
1.
2.
3.
TF + SA + BF = 130 rolling Scroll mode; see Section 6.2.24.1
TF + SA + BF = 131 non-rolling Scroll mode; see Section 6.2.24.2
TF + SA + BF = 132 non-rolling Scroll mode; see Section 6.2.24.3.
The recommended sequence for setting up the scroll modes is illustrated in Fig.13.
