S5935 – PCI Product
Pass-Thru Burst Reads
A Pass-Thru burst read operation occurs when a PCI
initiator reads multiple DWORDs from a Pass-Thru
region. A burst transfer consists of a single address
and a multiple data phases. During the address phase
of the PCI transfer, the S5935 stores the PCI address
Figure 85. Pass-Thru Burst Read
AMCC Confidential and Proprietary
into the Pass-Thru Address Register (APTA). If the
S5935 determines that the address is within one of its
defined Pass-Thru regions, it indicates to the Add-On
that a write to the Pass-Thru Data Register (APTD) is
required. Figure 6 shows a 6 data phase Pass-Thru
burst read access (Add-On write) using PTADR#.
