S5935 – PCI Product
Figure 7 also shows a 5 data phase Pass-Thru burst
read, but the Add-On logic uses PTRDY# to control
the rate at which data is transferred. In many applica-
tions, Add-On logic is not fast enough to provide data
every BPCLK (every 30 ns in a 33 MHz PCI system).
Figure 86. PCI Burst Read Controlled by PTRDY#
AMCC Confidential and Proprietary
In this example, the Add-On interface writes data
every other clock cycle. WR# is shown asserted during
the entire Add-On burst, but WR# can be deasserted
when PTRDY# is deasserted, the S5935 functions the
same under both conditions.
