• DMS: Destination Master Select
Identifies the Master Interface layer where the destination device (peripheral or memory) resides
Table 19-5.
• TT_FC: Transfer Type and Flow Control
The four following transfer types are supported:
• Memory to Memory, Memory to Peripheral, Peripheral to Memory and Peripheral to Peripheral.
The DMACA is always the Flow Controller.
• DST_SCATTER_EN: Destination Scatter Enable
Scatter on the destination side is applicable only when the CTLx.DINC bit indicates an incrementing or decrementing
address control.
• SRC_GATHER_EN: Source Gather Enable
Gather on the source side is applicable only when the CTLx.SINC bit indicates an incrementing or decrementing address
control.
• SRC_MSIZE: Source Burst Transaction Length
Number of data items, each of width CTLx.SRC_TR_WIDTH, to be read from the source every time a source burst transac-
tion request is made from either the corresponding hardware or software handshaking interface.
