The INCA-D supports fast register bank (context) switching. Multiple register banks can
physically exist within the internal DP-RAM at the same time. Only the register bank
selected 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.

The 16 word locations in the internal DP-RAM from 00’FCE0
the bit-addressable section) are provided as source and destination address pointers for
data transfers using 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).
