Onceamarkedlocationhasbeenset(andthedeviceisstillinretransmitmode,
MARK is HIGH), a retransmit can be initiated by a rising RCLK edge while the
retransmit input (
RT) is LOW. REN must be HIGH (reads disabled) before
bringing
RTLOW.Thedeviceindicatesthestartofretransmitsetupbysetting
OR HIGH.
When
OR goes LOW, retransmit setup is complete and on the next rising
RCLK edge after retransmit setup is complete, (
RTgoesHIGH),thecontents
of the first retransmit location are loaded onto the output register. Since FWFT
mode is selected, the first word appears on the outputs regardless of
REN, a
LOW on
RENis not required for the first word. Reading all subsequent words
requires a LOW on
REN to enable the rising RCLK edge. See Figure 19,
Retransmit from Mark timing (FWFT mode), for the relevant timing diagram.
Note, there must be a minimum of 32 bytes of data between the write pointer
and read pointer when the MARK is asserted. (32 bytes = 16 word = 8 long
words).Also,oncetheMARKisset,thewritepointerwillnotincrementpastthe
“marked” location until the MARK is deasserted. This prevents “overwriting” of
retransmitdata.
HSTL/LVTTL I/O
BoththewriteportandreadportareuserselectablebetweenHSTLorLVTTL
I/O, via two select pins, WHSTL and RHSTL respectively. All other control pins
are selectable via SHSTL, see Table 5 for details of groupings.
Note,thatwhenthewriteportisselectedforHSTLmode,theusercanreduce
the power consumption (in stand-by mode by utilizing the
WCS input).
All “Static Pins” must be tied to VCC or GND. These pins are LVTTL only,
and are purely device configuration pins.
