Section 17 IEBus™ Controller (IEB) [H8S/2552 Group]
17.3.20 IEBus Transmit Error Flag Register (IETEF)
IETEF checks the source of a TxE interrupt indicated in IETSR. This register detects an overflow
of a maximum number of bytes in one frame, arbitration loss, underrun error, timing error, and
NAK reception.

These bits are always read as 0 and cannot be modified.
Arbitration Loss
The IEB retransmits from the start bit for the number of
times specified by bits RN2 to Rn0 in IEMCR if the
arbitration has been lost in master communications. If the
arbitration has been lost for the specified number of times,
the AL and TxE flags are set to enter the wait state. If the
arbitration has been won within retransmit for the
specified number of times, this flag is not set to 1. This
flag is set only when the arbitration has been lost and the
wait state is entered.
[Setting condition]
•
[Clearing condition]
•
When the arbitration has been lost during data
transmission and the transmission has been
terminated
When writing 0 after reading AL = 1
