channel operation is provided through the PCI bus interface. The local bus interface
provides access to the internal mailbox. The MUNICH256 supports PCI PnP capability
by loading the subsystem ID and the subsystem vendor ID via a SPI interface into the
PCI configuration space.

The device consists of several macro functions as shown in Figure 3-1. The internal
modules are connected by busses/signals according to Infineons on-chip bus.
The main busses are:
• The initiator bus, on which the DMA requests of the data management units and the
• The configuration busses, which serve as the standard programming interface to
