A.1 Base Address and Offset Address Configuration

The base address configuration and the offset address to be generated by the Host varies according to the data width modes. For example, to address a region inside the Device starting from Addr[x:0], the following translation has to be used:

• Addr [x:n] should be programmed into the HICDBADDRx register
• Addr[n-1:0] should be used to generate address on the I/O HIC_A[7:0]

Where:

• n=8 for 16-bit data width mode
• n=7 for 8-bit data width mode

Table 8 captures various HICDBADDRx and I/O address offset combinations to be generated from the Host for different data width modes.
