PORT_ERR
[2] RW1C
This bit is set if the input port error recovery state machine encounters
an unrecoverable error or the output port error recovery state machine
enters the fatal_error state.
The input port error recovery state machine encounters an
unrecoverable error if it times out while waiting for a link-request after
sending a
packet-not-accepted
control symbol.
The output port error recovery state machine enters the fatal_error state
if the following sequence of events occurs:
1. The output port error recovery state machine enters the stop_output
state when it receives a
packet-not-accepted
control symbol. In
response, it sends the
input-status
link-request
/
input-status
(restart-from-error)
control symbol.
2. One of the following events occurs in response to the link-request
control symbol:
■ If the link-response is received but the
ackID
is outside of the
outstanding
ackID
set, or the
port_status
value is Error, then
the output port error recovery state machine enters the fatal_error
state.
■ If the port times out before receiving link-response, and the
number of times this time-out event has occurred reaches the
number you set in the RapidIO parameter editor as the value for
Link-request attempts, then the output port error recovery state
machine enters the fatal_error state.
When the
PORT_ERR
bit is set, the RapidIO IP core performs an internal
soft reset sequence, as described in “Fatal Errors” on page 4–62.
The
port_error
output signal mirrors this register bit.
1'b0
PORT_OK
[1] RO
Input and output ports are initialized and can communicate with the
adjacent device. This bit is asserted when
port_initialized
is
asserted and the following conditions exist:
■ The IP core has received at least 7 status control symbols.
■ The output port retry recovery state machine is not in the
stop_output state.
■ The output port error recovery state machine is not in the
stop_output state.
■ The input port retry recovery state machine is not in the stop_input
state.
■ The input port error recovery state machine is not in the stop_input
state.
1'b0
PORT_UNINIT
[0] RO
Input and output ports are not initialized and are in training mode. This
bit is the negation of the
PORT_OK
bit.
