RapidIO MegaCore Function

User Guide

You specify the initial value for the option in the RapidIO parameter editor, and
software can change it by modifying the value of the PROMISCUOUS_MODE bit in the Rx
Transport Control

register. Refer to

Table 6–51 on page 6–24

for information about

this register.

This parameter is not available for variations that target an Arria 10 device. RapidIO
IP core Arria 10 variations do not check destination IDs by default. However, you can
modify the PROMISCUOUS_MODE setting during normal operation.

Input/Output Maintenance Logical Layer Module

The I/O Maintenance Logical Layer Module parameters specify the interface to the
Maintenance Logical layer and the number of translation windows.

Maintenance Logical Layer

Maintenance logical layer interface(s)

selects which parts of the Maintenance Logical

layer to implement. You can specify any one of the following valid options:

Avalon-MM Master and Slave

Avalon-MM Master

(this option is not valid in Arria 10 variations)

Avalon-MM Slave

(this option is not valid in Arria 10 variations)

None

For variations that target an Arria 10 device. RapidIO IP core, only two of the values
are valid. Arria 10 variations either include a Maintenance Logical layer module
(Avalon-MM Master and Slave) or do not include a Maintenance Logical layer
module (None).

Transmit Address Translation Windows

Number of transmit address translation windows

is applicable only if you select

Avalon-MM Slave

or Avalon-MM Master and Avalon-MM Slave as the

Maintenance logical layer interface(s)

. You can specify a value from 1 to 16 to define

the number of transmit address translation windows supported.

This parameter is not available for variations that target an Arria 10 device. RapidIO
IP core Arria 10 variations that include a Maintenance Logical layer module have 16
Maintenance transmit address translation windows.

Port Write

The Port Write options control whether the Maintenance Logical layer module can
transmit or receive port-write requests. These options are available only if the
Maintenance Logical layer has an Avalon-MM slave port.

These options are not available independently for variations that target an Arria 10
device. RapidIO IP core Arria 10 variations that include a Maintenance Logical layer
module either support both reception and transmission of port-write requests., or do
not support port-write requests at all (neither reception nor transmission).
