Error Valid Bit When this bit is set, bits 1-6 include the

OBit 1: 15 are available for latching new of the erroneous channel (in case of OPB
error information. errors). Bits 11-15 indicate the type of
1 Bits 1: 15 contain last error. A new
error.
error cannot be latched.
In non-locked mode, the error indication
describes the last error that had occurred.
In locked mode, the error is the first one
that had occurred after this bit was
cleared.
This bit is set when an error occurs and
remains set until reset by the software. In
locked mode, new errors cannot be
latched in the error lock indication fields if
this bit is set
1 :6 CID
Channel
10
This field contains the number of the
channel which caused the locked error.
Bit 1 indicates whether the channel
10
represents an RX channel (1) or a TX
channel (0).
Bits 2:6 indicates the number of the
channel that caused the error.
Note: An error on the PLB cannot be
related to a channel. The error
condition may be resolved by using
the error information optionally
locked in the PLB slave.
