Functional Description
Configuration
Memory Pointer
Each channel in the PDCA has a set of configuration registers. Among these are the Memory
Address Register (MAR), the Peripheral Select Register (PSR) and the Transfer Counter Regis-
ter (TCR). The 32-bit Memory Address Register must be programmed with the start address of
the memory buffer. The register will be automatically updated after each transfer to point to the
next location in memory. The Peripheral Select Register must be programmed to select the
desired peripheral/handshake interface. The Transfer Counter Register determines the number
of data items to be transferred. The counter will be decreased by one for each data item that has
been transferred.
Both the Memory Address Register and the Transfer Counter Register can be read at any time
to check the progress of the transfer.
Each channel has also reload registers for the Memory Address Register and the Transfer
Counter Register. When the TCR reaches zero, the values in the reload registers are loaded into
MAR and TCR. In this way, the PDCA can operate on two buffers for each channel.
Each channel has a 32-bit Memory Pointer Register (MAR). This register holds the memory
address for the next transfer to be performed. The register is automatically updated after each
