VIP Phases
Figure 2–28 illustrates an example of a typical VIP transfer and Table 2–5 describes the sequence of phases involved
in the VIP data transfer.

signal data is ready for
the next phase
GUI must
drive this low
during idle
Slave drives high
if transfer is not
terminated in
cycle 1
FRAME and/or VSTOP drive
low to terminate the transfer
Slave may drive DTACK
low for the next byte. It
is irrelevant as transfer is
already terminated
VSTOP can drive low to
terminate the transfer. If
terminated there will be
no data phase
