DMA operations, both peripheral and memory DMA, supporting
both linear and two-dimensional transfer types. Specific function-
ality allows the application to:
• Set and detect the mapping of DMA channels to
peripherals.
• Configure individual DMA channels for inbound/outbound
traffic using circular (autobuffered) DMA or descrip-
tor-based DMA.
• Command the DMA manager to issue live or deferred
callbacks upon DMA completions.
• Queue descriptors, intermixing linear and two-dimensional
transfers on DMA channels.
• Enable the DMA manager to loopback on descriptor chains
automatically.
• Stream data continuously into or out of a memory stream or
peripheral.
• Initiate linear and two-dimensional memory DMA transfers
with simple C-like,
• Programmable Flag Service – The programmable flag service
provides a simple interface into the programmable flags, sometimes
called general-purpose I/O, of the Blackfin processor. This allows
