External Bus Interface
9.5.8.7
This signal is sent from the master to the slave to indicate that there is a data beat following the current
data beat. The master uses this signal to give the slave advance warning of the remaining data in the burst.
BDIP can also be used to terminate the burst cycle early. Refer to
Section 9.5.5, “Burst
Base Registers
9.5.9
The EBI uses three termination signals:
9.5.9.1
Transfer acknowledge (TA) indicates normal completion of the bus transfer. During a burst cycle, the slave
asserts this signal with every data beat returned or accepted.
9.5.9.2
A slave sends the BI signal to the master to indicate that the addressed device does not have burst
capability. If this signal is asserted, the master must transfer in multiple cycles and increment the address
for the slave to complete the burst transfer. For a system that does not use the burst mode at all, this signal
can be tied low permanently. Refer to
for BI options.
9.5.9.3
The TEA signal terminates a bus cycle under one or more bus error conditions. The current bus cycle must
be aborted. This signal overrides any other cycle termination signals, such as transfer acknowledge.
9.5.9.4
The transfer protocol was defined to avoid electrical contention on lines that can be driven by various
sources. To this end, a slave must not drive signals associated with the data transfer until the address phase
is completed and it recognizes the address as its own. The slave must disconnect from signals immediately
after it has acknowledged the cycle and no later than the termination of the next address phase cycle. This
means that the termination signals must be connected to power through a pull-up resistor to avoid the
situation in which a master samples an undefined value in any of these signals when no real slave is
addressed.
