The BIST state machine has multiple states, as shown in
Figure 2 and Table 16. When the receive PLL detects an
out-of-lock condition, the BIST state is forced to the
Start-of-BIST state, regardless of the present state of the BIST
state machine. If the number of detected errors ever exceeds
the number of valid matches by greater than 16, the state
machine is forced to the WAIT_FOR_BIST state where it
monitors the interface for the first character (D0.0) of the next
BIST sequence. Also, if the Elasticity Buffer ever hits and
overflow/underflow condition, the status is forced to the
BIST_START until the buffer is re-centered (approximately
nine character periods).
To ensure compatibility between the source and destination
systems when operating in BIST, the sending and receiving
ends of the BIST sequence must use the same clock setup
(RXCKSEL = MID or RXCKSEL = LOW).

Normal Character Received. The valid Data character on the output bus
meets all the formatting requirements of Data characters listed in Table 20.
Special Code Detected. The valid special character on the output bus
meets all the formatting requirements of the Special Code characters listed
in Table 21, but is not the presently selected framing character or a Decoder
violation indication.
Receive Elasticity Buffer
Underrun/Overrun Error. The
receive buffer was not able to
add/drop a K28.5 or framing
character.
Framing Character Detected. This indicates that a character matching the
patterns identified as a framing character (as selected by FRAMCHAR) was
detected. The decoded value of this character is present on the output bus.
Codeword Violation. The character on the output bus is a C0.7. This
indicates that the received character cannot be decoded into any valid
character.
PLL Out of Lock. This indicates a PLL Out of Lock condition.
Running Disparity Error. The character on the output bus is a C4.7, C1.7,
or C2.7.

JTAG Support
The CYP(V)(W)15G0101DXB contains a JTAG port to allow
system level diagnosis of device interconnect. Of the available
JTAG modes, only boundary scan is supported. This capability
is present only on the LVTTL inputs, LVTTL outputs and the
REFCLK± clock input. The high-speed serial inputs and
outputs are not part of the JTAG test chain.
JTAG ID
The JTAG device ID for the CYP(V)(W)15G0101DXB is
“1C804069”x.
3-Level Select Inputs
Each 3-Level select input reports as two bits in the scan
register. These bits report the LOW, MID, and HIGH state of
the associated input as 00, 10, and 11, respectively.

invalid.
BIST Start. Receive BIST is
enabled on this channel, but
character compares have not
yet commenced. This also
indicates a PLL Out of Lock
condition, and Elasticity Buffer
overflow/underflow conditions.
BIST Error. While comparing
characters, a mismatch was
found in one or more of the
decoded character bits.
BIST Wait. The receiver is
comparing characters. but has
not yet found the start of BIST
character to enable the LFSR.
