Table 6–16. LP-Serial Lane Register Block Header—0x200
Field Bits
Access
Function
Default
EF_PTR
[31:16] RO
Hard-wired pointer to the next block in the data structure, if one exists.
If this IP core variation instantiates the Error Management Extensions
registers, the value in this field is the address of the Error Management
Extended Features block, which is 0x300. If this IP core variation does
not instantiate the Error Management Extensions registers, the value of
this field is determined by the Extended features pointer parameter in
the RapidIO II parameter editor.
EF_ID
[15:0]
RO
Hard-wired extended features ID.
16'h000D
Table 6–17. LP-Serial Lane n Status 0—Offset: 0x210, 0x230, 0x250, 0x270 (Part 1 of 2)
Field Bits
Access
Function
Default
Port Number
[31:24] RO
The number of the port within the IP core to which the lane is assigned.
The RapidIO II IP core implements only a single RapidIO port, so this
field always has the value of 0.
8’h0
Lane Number
[23:20]
RO
The number of the lane in the port.
4’hn
Transmitter
Type
[19]
RO
Transmitter type.
1’b0: Short run.
1’b1: Long run.
This value is identical for all lanes of the port.
Transmitter
Mode
[18]
RW
Transmitter operating mode.
1’b0: Short run.
1’b1: Long run.
The value in this field is identical for all lanes and is identical to the value
of the Transmitter Type field. The value in this field does not affect
the physical transceiver. Software must modify this bit if relevant
physical transceiver properties change.
Receiver Type
[17:16]
RO
Receiver type.
2’b00: Short run.
2’b01: Medium run.
2’b10: Long run.
2’b11: Reserved.
This value is identical for all lanes of the port.
Receiver
Input
Inverted
[15]
RO
Indicates that the lane receiver has detected that the polarity of its input
signal is inverted, and has inverted the receiver input to correct the
polarity. A value of 1’b0 indicates the receiver input is not inverted.
The RapidIO II IP core does not support automatic detection of inverted
inputs, and this field always has the value of 0.
1’b0
