Implementation
Defined
[1:0] RO Reserved for this implementation 2'b00
Notes to Table 6–29 :
(1) If one of the Logical layers supported by the RapidIO II IP core is not selected, the corresponding bits in the Destination Operations CAR are
set to zero by default.
(2) The 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 Destination operations CAR override in the RapidIO II parameter editor.
(3) The default value is 1'b1 if you turn on Enable I/O Logical layer Master module in the RapidIO II parameter editor. The default value is 1'b0
if you turn off Enable I/O Logical layer Master module in the RapidIO II parameter editor.
(4) The default value is 1'b1 if you turn on Enable Doorbell support in the RapidIO II parameter editor. The default value is 1'b0 if you turn off
Enable Doorbell support in the RapidIO II parameter editor.
(5) The default value is 1'b1 if you turn on Enable Maintenance module in the RapidIO II parameter editor. The default value is 1'b0 If you turn
off Enable Maintenance module.
Table 6–29. Destination Operations CAR—Offset: 0x1C (1) , (2) (Part 2 of 2)
Field Bits Access Comment Default
Table 6–30. Switch Route Table Destination ID Limit CAR—Offset: 0x34 (1)
Field Bits Access Function Default
RSRV [31:16] RO Reserved 16'h0
Max_destID [15:0] RO
Maximum configurable destination ID. Value is the
maximum number of destination IDs, minus one.
(2)
Note to Table 6–30 :
(1) If the Standard route table configuration support bit or the Extended route table configuration support bit in the Processing Element
Features CAR is set, user logic must implement the functionality and registers to support the standard or extended route table configuration.
The RapidIO II IP core does not implement the Standard Route CSRs at offsets 0x70, 0x74, and 0x78.
(2) The default value is set in the RapidIO II parameter editor.
Table 6–31. Data Streaming Information CAR—Offset: 0x3C (1)
Field Bits Access Function Default
MaxPDU [31:16] RO
Indicates the maximum PDU size that this destination end point
supports. Unit is bytes.
(2)
SegSupport [15:0] RO
Indicates the number of segmentation contexts that this
destination end point supports.
16'h0000 – 65536 segmentation contexts
16'h0001 – 1 segmentation context
16'h0002 – 2 segmentation contexts
...
16’hFFFF – 65535 segmentation contexts
(2)
Note to Table 6–31 :
(1) User logic must implement the functionality and registers to support data streaming configuration. The values in this register do not affect the
IP core.
(2) The default value is set in the RapidIO II parameter editor.
