Data Sheet
PECXCx (FEFy
PEC Extended Control Register Addresses
Source and destination pointers specifiy the locations between which the data is to be
moved. For PEC transfer description refer to Chapter 7.3, page 115, where the PEC
operation is descriped more in detail.
Channel Link Mode for Data Chaining
Data chaining with linked PEC channels is enabled, if the Channel Link Control Bit in
PECCx register is set to ’1’, either in one or both PEC channel control registers of a
channel pair. In this case, two PEC channels are linked together and handle chained
block transfers alternatively to each other. The whole data transfer is divided into several
block transfers where each block is controlled by one PEC channel of a channel pair.
When a data block is completely transferred a channel link interrupt is generated and
the PEC service request processing is automatically switched to the ’other’ PEC channel
of the channel-pair. Thus, PEC service requests addressed to a linked PEC channel are
either handled by linked PEC channel A or by linked PEC channel B. This channel toggle
allows to set up shadow and multiple buffers for PEC transfers by changing pointer and
count values of one channel while the other channel is active. The following table list the
channels that can be linked together and the channel numbers to address the linked
channels.
