the previous context. The number of implemented register banks (arbitrary sizes) is
limited only by the size of the available internal RAM.
Details on using, switching, and overlapping register banks are described in
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).
Figure 3-4
Whenever a PEC data transfer is performed, the pair of source and destination pointers
(selected by the specified PEC channel number) is accessed independently of the
current DPP register contents. The locations referred to by these pointers are accessed
independently of the current DPP register contents as well. If a PEC channel is not used,
the corresponding pointer locations are available and can be used for word or byte data
storage.
