Data Sheet
by the Context Pointer register (CP) is active at a given time, however. Selecting a new
active register bank is simply done by updating the CP register. A particular Switch
Context (SCXT) instruction performs register bank switching and an automatic saving of
the previous context. The number of implemented register banks (arbitrary sizes) is only
limited by the size of the available internal RAM.
Details on using, switching and overlapping register banks are described in chapter
“System Programming”.
PEC Source and Destination Pointers
The 16 word locations in the internal RAM from 00’FCE0
bit-addressable section) are provided as source and destination address pointers for
data transfers on the eight PEC channels. Each channel uses a pair of pointers stored
in two subsequent word locations with the source pointer (SRCPx) on the lower and the
destination pointer (DSTPx) on the higher word address (x = 7...0).
