External Bus Interface
9.5.8.5
The transfer size signals (TSIZ[0:1]) indicate the size of the requested data transfer. During each transfer,
the TSIZ signals indicate how many bytes are remaining to be transferred by the transaction. The TSIZ
signals can be used with BURST and ADDR[30:31] to determine which byte lanes of the data bus are
involved in the transfer. For non-burst transfers, the TSIZ signals specify the number of bytes starting from
the byte location addressed by ADDR[30:31]. In burst transfers, the value of TSIZ is always 00.
9.5.8.6
The address type (AT[0:3]), program trace (PTR), and reservation transfer (RSV) signals are outputs that
indicate one of 16 address types. These types are designated as either a normal or alternate master cycle,
user or supervisor, and instruction or data type. The address type signals are valid at the rising edge of the
clock in which the special transfer start (STS) signal is asserted.
A special use of the PTR and RSV signals is for the reservation protocol described in
“Storage
