A.1 HPI Overview
The HPI layer performs these key functions:
from the register details and bit manipulation.
The CX29600 device is highly flexible and configurable. The initialization
component of the HPI provides a simple and efficient means of initializing the
device to a default state.
device in any of the supported modes of operation.
enabled or disabled during run time, while others should not be configured at any
time other than during the initialization process.
The CX29600 device provides extensive SONET/SDH overhead processing
capabilities. The CX29600 HPI allows the user to use these capabilities for
Section, Line, and Path overhead processing, as well as error insertion and other
capabilities.
The CX29600 HPI allows the user to configure interrupts and process received
interrupts indicators. The HPI accommodates polling of status registers.
The CX29600 allows the user to inject various types of errors into the following
transmitted SONET overhead bytes: A1, B1, B2, B3, M1 and G1.
The CX29600 HPI allows the user to enable and disable Source and Line
loopbacks on the device.
