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.

One: BOV active

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.

One: ACKE active

Zero: ACKE inactive
