Small Accesses (Small Port Size and Short Burst Length)

In this context, a small access refers to an access whose burst length and port size are such that the number
of bytes requested by the internal master cannot all be fetched (or written) in one external transaction. This
is the case when the base register’s burst length bit (EBI_BR

n

[BL]) and port size bit (EBI_BR

n

[PS]) are

set such that one of two situations occur:

•

Burst accesses are inhibited and the number of bytes requested by the master is greater than the 
port size (16 or 32 bit) can accommodate in a single access.

•

Burst accesses are enabled and the number of bytes requested by the master is greater than the 
selected burst length (4 words or 8 words).

If this is the case, the EBI initiates multiple transactions until all the requested data is transferred. It should
be noted that all the transactions initiated to complete the data transfer are considered as an atomic
transaction, so the EBI does not allow other unrelated master accesses to intervene between the transfers.
In external master mode, this means that the EBI keeps BB asserted and does not grant the bus to another
master until the atomic transaction is complete.

Table 12-16

 shows all the combinations of burst length, port size, and requested byte count that cause the

EBI to run multiple external transactions to fulfill the request.

In most cases, the timing for small accesses is the same as for normal single-beat and burst accesses, except
that multiple back-to-back external transfers are executed for each internal request. These transfers have
no additional dead cycles in-between that are not present for back-to-back stand-alone transfers except for
the case of writes with an internal request size greater than 64 bits, discussed in 

Section 12.4.2.6.2, “Small

Access Example #2: 32-byte Write with External TA

.”

The following sections show a few examples of small accesses. The timing for the remaining cases in

Table 12-16

 can be extrapolated from these and the other timing diagrams in this document.

In 32-bit data bus mode (DBM=0 in EBI_MCR), two accesses are performed. In 16-bit data bus mode 
(DBM=1), one 2-beat burst access is performed and this is not considered a small access case. See 

Section 12.4.2.11, “Non-Chip-Select Burst in 16-bit Data Bus Mode

” for this special DBM=1 case.
