21050 PCI-to-PCI Bridge Hardware Implementation
Application Note
11
Use these pins to block forwarding of interrupts until all posted write data is flushed. You can do
this by enabling and disabling write posting dynamically by setting the Disable Posting bit in the
21050 configuration space and controlling the s_dispst_l pin.
Although use of the data synchronization pins is not specified,
Figure 2
is an example of a possible
implementation. This example assumes that an interrupt edge from a device causes s_dispst_l to
assert to the 21050, marking any posted write data and disabling write posting. As soon as the
marked write data is flushed, indicated by the deassertion of s_bufne_l, the interrupt is forwarded
and s_dispst_l deasserts, enabling write posting again. Note that s_bufne_l is not valid until two
cycles after the s_dispst_l assertion. Interrupt deassertion is always forwarded immediately. You
can implement this logic in an external PAL. In this application the Disable Posting bit must be set.
During initialization, set the Disable Posting bit in the 21050 implementation-specific
configuration space.
