Note For the burst mode, the SLRD and SLOE are left asserted during the entire duration of the read. In the burst read mode, when
SLOE is asserted, data indexed by the FIFO pointer is on the data bus. During the first read cycle, on the rising edge of the clock the
FIFO pointer is updated and increments to point to address N+1. For each subsequent rising edge of IFCLK, while the SLRD is
asserted, the FIFO pointer is incremented and the next data value is placed on the data bus.

nizing clock. This diagram illustrates a single write followed by
burst write of 3 bytes and committing all 4 bytes as a short packet
using the PKTEND pin.

Note t
running at 48 MHz, the FIFO address setup time is more than
one IFCLK cycle.
At t = 0 the FIFO address is stable and the signal SLCS is
asserted (SLCS may be tied low in some applications).
At t = 1, the external master or peripheral must output the data
value onto the data bus with a minimum set up time of t
before the rising edge of IFCLK.
At t = 2, SLWR is asserted. The SLWR must meet the setup
time of t
edge of IFCLK) and maintain a minimum hold time of t
from the IFCLK edge to the deassertion of the SLWR signal).
If SLCS signal is used, it must be asserted with SLWR or before
SLWR is asserted. (that is the SLCS and SLWR signals must
both be asserted to start a valid write condition).
While the SLWR is asserted, data is written to the FIFO and on
the rising edge of the IFCLK, the FIFO pointer is incremented.

The same sequence of events are also shown for a burst write
and are marked with the time indicators of T = 0 through 5.
Note For the burst mode, SLWR and SLCS are left asserted for
the entire duration of writing all the required data values. In this
burst write mode, after the SLWR is asserted, the data on the
FIFO data bus is written to the FIFO on every rising edge of
IFCLK. The FIFO pointer is updated on each rising edge of
IFCLK. In
SLWR is deasserted. The short 4-byte packet is committed to the
host by asserting the PKTEND signal.
There is no specific timing requirement that must be met for
asserting the PKTEND signal with regards to asserting the
SLWR signal. PKTEND is asserted with the last data value or
thereafter. The only consideration is the setup time t
hold time t
number of data values committed includes the last value written
to the FIFO. In this example, both the data value and the
PKTEND signal are clocked on the same rising edge of IFCLK.
PKTEND is asserted in subsequent clock cycles. The
FIFOADDR lines must be held constant during the PKTEND
assertion.

The FIFO flag is also updated after a delay of t
