Multi-Channel (MCH) PLBv46 Slave Burst (v1.00a)
C_PLB_ARD_ADDR_RANGE_ARRAY. Therefore, the User IP address ranges accessible by both the
MCH interfaces and the PLB should occur first in C_PLB_ARD_ADDR_RANGE_ARRAY. Also, the
order in which the address ranges are specified in the C_PLB_ARD_ADDR_RANGE_ARRAY and the
C_MCH_USERIP_ADDRRANGE_ARRAY must be the same so that the chip selects to the User IP
address ranges will be consistent between the PLB interface and the MCH interfaces. Note that it is
assumed that all User IP address ranges accessible through the MCH interfaces are also accessible
through the PLB interface.
Parameter/Port Dependencies
The dependencies between the MCH_PLBv46_Slave_Burst design parameters and I/O signals are
shown in Table 3. It gives information about how the ports and parameters get affected by changing
certain parameters.
