Disable Destination ID Checking
Disable destination ID checking by default determines the default value of the
option to route a request packet with a supported ftype but a destination ID not
assigned to this endpoint. The effect of this option is detailed in
“Transport Layer” on
page 4–70 .
You specify the initial value for the option in the RapidIO II parameter editor, and
software can change it by modifying the value of the DIS_DEST_ID_CHK field of the
Port 0 Control CSR
. Refer to Table 6–15 on page 6–17 for information about this
register.
By default, this parameter is turned off.
Logical Layer Settings
The Logical layer settings specify properties of the following Logical layer modules:
■ Maintenance module
■ Doorbell module
■ I/O master module
■ I/O slave module
Maintenance Configuration Settings
The Maintenance module settings specify properties of the Maintenance Logical layer.
If you turn on Enable Maintenance module, a Maintenance module is configured in
your RapidIO II IP core.
If the Maintenance module is enabled, the Maintenance address bus width
parameter is available to determine the Maintenance slave interface address bus
width. This parameter currently supports only a 26-bit address width.
This parameter controls the width of the Maintenance slave interface address bus
only. The Maintenance master interface address bus is 32 bits wide.
The Maintenance module supports RapidIO MAINTENANCE read and write operations
and MAINTENANCE port-write operations. For more information about the
Maintenance module, refer to
“Maintenance Module” on page 4–32 .
Doorbell Configuration Settings
The Doorbell module settings specify properties of the Doorbell Logical layer module.
If you turn on Enable Doorbell support, a Doorbell module is configured in your
RapidIO II IP core to support generation of outbound RapidIO DOORBELL messages
and reception and processing of inbound DOORBELL messages.
If this parameter is turned off, received DOORBELL messages are routed to the Avalon-
ST pass-through interface if it is enabled, or are silently dropped if the pass-through
interface is not enabled.
