8.0 Register Set
The registers shown in this section provide access for configuration, alarm monitoring, and control
of the chip. Table 59 “MAC Control Registers ($ Port Index + Offset)” on page 156 through
Table 69 “Optical Module Registers ($ 0x799 - 0x79F)” on page 162 provide register map details.
The registers are listed by ascending address in the table.
8.1 Document Structure
The following sections are structured to provide a general overview of the register map. Later
sections provide detailed descriptions of each register segment or bit.
All registers are accessed and addressed as 32-bit doublewords. When accessed using 8- or 16-bit
accesses, the CPU interface packs or unpacks the partial accesses into a 32-bit register value.
8.2 Graphical Representation
Figure 53 represents an overview of the IXF1104 MAC global control status registers that are used
to configure or report on all ports. All register locations shown in Figure 53 represent a 32-bit
double word.
