Rolling Scroll mode
The RAM-to-display mapping for the rolling Scroll mode
when a 132
×
130 (columns
×
rows) display is connected
to the PCF8833 is illustrated in Fig.14. In this case rows
0 and 131 must be left open. When a 132
×
132 display is
connected, there will be a one-to-one mapping between
the RAM and the display, and there will be no unused
rows.
The rolling Scroll mode is activated when the Set Entry
Scroll Point (SEP) is set; see Table 35.
Figure 15 gives an example for when the PCF8833 is
working in the rolling Scroll mode.
When the rolling Scroll mode is used the following
sequence can be applied:
After the desired time interval increment the scroll
address to SEP + n for a n-line step
Keep incrementing the scroll address (SEP) at regular
intervals.
The rolling Scroll mode is left when the normal Display
mode on (NORON) or the partial Display mode on
(PTLON) is selected.
