10.0 Local Processor Interface
10.1 Overview
The CN8236 integrated circuit can be used in conjunction with an external
processor that performs initialization, link management, monitoring, and control
functions. The local processor interface consists of a loosely coupled architecture
that interfaces to the CN8236 through bidirectional transceivers and buffers
controlled by the local processor and the CN8236, as shown in
architecture allows the processor access to all of the CN8236 SAR-shared
memory and control registers, while insulating the CN8236 from processor
instruction and data cache fills. This also allows the local processor the option to
control multiple CN8236 and/or physical interface devices.
