The address and byte enable signals on the PCI bus are mapped to the local bus
according to table 5-4 and table 5-5. It can be seen that the MUNICH256 supports
different valid C/BE combinations which result in either a 8- or 16-bit access to the local
bus interface. All accesses not shown in the table result in generation of a ’PCI Access
Error’ interrupt vector. Byte swapping for 16 bit data transfers can be disabled.

Table 5-5
5.4
The serial interface of the interface can be configured in a 16-port mode and additionally
in a 28-port mode. Dependent on the port configuration (16-port mode or 28-port mode)
the MUNICH256 supports T1, E1, channelized 4.096 MHz, channelized 8.192 MHz or
unchannelized frame structures (Figure 5-9 ).
