PCI Write Transfers
Write transfers on the PCI bus are one clock period
shorter than read transfers. This is because the
AD[31:0] bus does not require a turn-around cycle
between the address and data phases. When the
S5335 is accessed (target), it responds to a PCI bus
memory or I/O transfers. As a PCI initiator, the S5335
controller can also execute PCI memory write
operations.
The timing diagram in Figure 49 represents an S5335
initiator PCI write operation transferring to a fast, zero-
wait-state memory target. The signals driven by the
S5335 during the transfer are FRAME#, AD[31:0], C/
BE[3:0]#, and IRDY#. The signals driven by the target
are DEVSEL# and TRDY#. As with PCI reads, targets
assert DEVSEL# and TRDY# after the clock defining
the end of the address phase (boundary of clock peri-
ods 1 and 2 of Figure 49). TRDY# is not driven until
the target has accepted the data for the PCI write.
When the S5335 becomes the PCI initiator, it attempts
sustained zero-wait state burst writes until one of the
following occurs:
The memory target aborts the transfer
PCI bus grant (GNT# is removed)
The Add-On to PCI FIFO becomes empty
A higher priority (PCI to Add-On) S5335 trans-
fer is pending (if programmed for priority)
The write transfer byte count reaches zero
Bus mastering is disabled from the Add-On
interface
Write accesses to the S5335 operation registers
(S5335 as a target) are shown in Figure 50. Here, the
S5335 asserts the signal STOP# in clock period 3.
STOP# is asserted because the S5335 supports fast,
zero-wait-state write cycles but does not support burst
writes to operation registers. Wait states may be
added by the initiator by not asserting the signal
IRDY# during clock 2 and beyond. There is only one
condition where writes to S5335 operation registers do
not return TRDY# (but do assert STOP#). This is
called a target-initiated termination or target discon-
nect and occurs when a write attempt is made to a full
S5335 FIFO. As with the read transfers, the assertion
of STOP# without the assertion of TRDY# indicates
the initiator should retry the operation later.
