TSLP and TDMA continue normal processing. If the TDMA does not get more data from shared memory
before the TSLP needs to output the next data bit, TSLP outputs another octet of flag or idle code.
The user wants to abort the transmission of the current message. For details, please see
To provide a mechanism for the self-served transmitter to recover from a receiver error. For details, please see
Chapter
CX28500 stops transmitting the current message, sends out an ABORT sequence, and goes on to process the
next message, if it exists.
One message is split across multiple shared memory buffers. CX28500 reached the end of a buffer by
servicing (writing) the number of bytes equal to BLEN specified in the Receive Buffer Descriptor.
EOB Interrupt (if EOBIEN = 1 in Receive Buffer Descriptor).
RDMA and RSLP continue normal processing.
RSLP has detected the end of a message (closing flag or an error condition). Error conditions include:
Overflow, COFA, OOF, Abort, Too Long, Alignment, and FCS error.
If there were no errors, RxEOM interrupt (if EOMIEN = 1 in

RDMA and RSLP continue normal processing.
RSLP detected received data changed from flag (7Eh) octets to abort code (zero followed by fourteen
consecutive ones) in the idle code section of the bit stream and not in the message payload section. An abort
code detection in the message payload results in an ABORT Termination Error.
