15.0 SAR Initialization—Example Tables
NOTE:
The following tables provide an example CN8237 SAR initialization of control
registers, internal memory control structures, and external memory control
structures.
15.1 Segmentation Initialization
Before segmentation is enabled, the host must allocate and initialize all of the
segmentation control registers.
Initializing the CN8237 SAR is a complex procedure. Mindspeed offers an
optional (ANSI C) software package which performs SAR device
initialization and programmability. This is the recommended approach for
SAR initialization.
The PCI address of these structures is (Register_Value
SEG_MEMORY_BASE_ADDRESS.
