User Guide
■ Illegal Transaction Decode is declared for malformed received response packets
occurring from any of the following events:
■
NREAD
or
NWRITE_R
response packet with status not
DONE
nor
ERROR
.
■
NWRITE_R
response packet with payload or with a transaction type indicating
the presence of a payload.
■
NREAD
response packet without payload, with incorrect payload size, or with a
transaction type indicating absence of payload.
Registers in the Implementation Defined Space
The I/O Avalon-MM slave module defines the
Input/Output Slave Interrupt
registers with the following bits. For details on when these bits are set, refer to their
descriptions in Table 6–60 on page 6–40.
■
INVALID_READ_BURSTCOUNT
■
INVALID_READ_BYTEENABLE
■
INVALID_WRITE_BYTEENABLE
■
INVALID_WRITE_BURSTCOUNT
■
WRITE_OUT_OF_BOUNDS
■
READ_OUT_OF_BOUNDS
When any of these bits are set, the system interrupt signal
io_s_mnt_irq
is also
asserted if the corresponding bit in the
Input/Output Slave Interrupt Enable
register (Table 6–61 on page 6–41) is set.
The Avalon-MM Slave Interface's Error Indication Signal
The
ios_rd_wr_readresponse
output is asserted when a response with
ERROR
status is
received for an
NREAD
request packet, when an
NREAD
request times out, or when the
Avalon-MM address falls outside of the enabled address mapping window. As
required by the Avalon-MM interface specification, a burst in which the
ios_rd_wr_readresponse
signal is asserted completes despite the error signal
assertion.
Input/Output Avalon-MM Master
The I/O Avalon-MM master module processes the request packets that it receives and
generates response packets when required. Anomalies are reported through one or
both of the following two channels:
■ Standard error management registers
■ Response packets with
ERROR
status
Standard Error Management Registers
The following two standard defined error types can be declared by the
I/O Avalon-MM master module. The corresponding bits are then set and the required
packet information is captured in the appropriate error management registers.
