PEC Control Register Addresses
Byte/Word Transfer bit BWT controls, if a byte or a word is moved during a PEC service
cycle. This selection controls the transferred data size and the increment step for the
modified pointer.
Increment Control Field INC controls, if one of the PEC pointers is incremented after
the PEC transfer. It is not possible to increment both pointers, however. If the pointers
are not modified (INC=’00’), the respective channel will always move data from the same
source to the same destination.
Note: The reserved combination ‘11’ is changed to ‘10’ by hardware. However, it is not
The PEC Transfer Count Field COUNT controls the action of a respective PEC channel,
where the content of bit field COUNT at the time the request is activated selects the
action. COUNT may allow a specified number of PEC transfers, unlimited transfers or no
PEC service at all.
The table below summarizes, how the COUNT field itself, the interrupt requests flag IR
and the PEC channel action depends on the previous content of COUNT.

Action of PEC Channel
and Comments
Move a Byte / Word. Continuous transfer mode, ie.
COUNT is not modified
Move a Byte / Word and decrement COUNT
Move a Byte / Word. Leave request flag set, which
triggers another request
No action! Activate interrupt service routine rather
than PEC channel.
