The following figure shows a typical burst write access.
The PCnet-PCI II controller arbitrates for the bus, is
granted access, and writes four 32-bit words (DWords)
to the system memory and then releases the bus. In this
example, the memory system extends the data phase of
the first access by one wait state. The following three

data phases take one clock cycle each, which is deter-
mined by the timing of TRDY. The example assumes
that EXTREQ (BCR18, bit 8) is set to ONE, therefore,
REQ is not deasserted until the next to last data phase
is finished.
