NRTR [3:0]:
Number of retries done successfully in transmission. In case of reception NRTR[3:0] is
undefined.
IDTR [3:0]:
Channel number that was successfully transmitted, received or exceeded its retry count.
Last Error Status Register
(0x07)
Read only register.
Default value after reset: 0
×
00.
The Last Error Status Register contains the error code for the last transmission or
reception attempt. It is updated after each attempt, i.e. several error codes can be
reported during one single transmission (with several retries).
BOC: Buffer Occupied
When one channel configured in “Reply request” mode has its “received” bit set
when it attempts to transmit its request.
BOC with the link capability between two channels sharing the same received buffer
is set when one channel has already set its “received” bit in its “Message length and
status Channel register” and a receive is attempted on the other one.
BOV: Buffer Overflow
BOV indicates that the buffer length setup in the Channel Status Register was shorter
than the number of bytes received plus 1, therefore, some data got lost.

Zero
: BOV inactive
FCSE: Framing Check
Sequence Error
FCSE indicates a mismatch between the FCS received and the FCS calculated
One
: FCSE active
Zero:
FCSE inactive
ACKE: Acknowledge Error
ACKE indicates a physical violation or collision on ACK field of the frame when the
TSS463 is produced.
