Destination Operations CAR
The Destination operations CAR override parameter supports user input to the
values of all of the fields of the Destination Operations CAR (
Table 6–29 on
page 6–30 ). You can use this parameter to specify that your RapidIO II IP core
variation handles some specific functionality through the Avalon-ST pass-through
port.
The 32-bit default value of the Destination Operations CAR is determined by the
functionality you enable in the RapidIO II IP core with other settings in the parameter
editor. For example, if you turn on Enable Maintenance module, the PORT_WRITE field
is set by default to the value of 1’b1. However, the actual reset value of the
Destination Operations
CAR is the result of the bitwise exclusive-or operation
applied to the default values and the value you specify for the Destination operations
CAR override
parameter.
For example, by default, the Data Message field of this CAR is turned off. However,
you can set the value of the Destination operations CAR override parameter to
32’h00000800 to override the default value of the Data Message field, to indicate that
user logic attached to the Avalon-ST pass-through interface supports data message
operations that the RapidIO II IP core receives on the RapidIO link. The RapidIO II IP
core supports reporting of data-message related errors through the standard Error
Management Extensions registers.
