Non-rolling Scroll mode
The RAM-to-display mapping for the non-rolling Scroll
mode when a 132
×
130 (columns
×
rows) display is
connected to the PCF8833 is illustrated in Fig.16. In this
case unused rows and columns are to be left open, for
instance row 0 and 131. If a 132
×
132 display is
connected to the PCF8833 the content of row 0 and 131
will be the same as the content which is displayed in row 1
and 130, respectively. By doing so, the display data RAM
will have 1 row in the background, whose content can be
updated when it is not displayed.
The non-rolling Scroll mode is activated when the Set
Entry Scroll point is set; see Table Fig.36.
An example is given in Figure 17 for the case when the
PCF8833 is working in the non-rolling Scroll mode
(TF + SA + BF = 131).
When the non-rolling Scroll mode is used the following
sequence can be applied:
Fill the background memory
After the desired time interval increment the scroll
address to SEP + n for a n-line step
Keep filling the background memory and incrementing
scroll address (SEP) at regular intervals to obtain a
smooth scrolling.
Thenon-rollingScrollmodeisleftwhenthenormalDisplay
mode on (NORON) or the partial Display mode on
(PTLON) is selected.
