Source and destination pointers specifiy the locations between which the data is to be
moved. A pair of pointers (SRCPx and DSTPx) is associated with each of the 8 PEC
channels. These pointers do not reside in specific SFRs, but are mapped into the internal
RAM of the C161U just below the bit-addressable area (see figure below).
Figure 22
PEC data transfers do not use the data page pointers DPP3...DPP0, see also
Chapter 5.5, "PEC - Extension of Functionality". The PEC source and destination
pointers are used as 16-bit intra-segment addresses within segment 0, so data can be
transferred between any two locations within the first four data pages 3...0.
The pointer locations for inactive PEC channels may be used for general data storage.
Only the required pointers occupy RAM locations.
Note: If word data transfer is selected for a specific PEC channel (ie. BWT=’0’), the
Data Sheet
respective source and destination pointers must both contain a valid word address
which points to an even byte boundary. Otherwise the Illegal Word Access trap will
be invoked, when this channel is used.
