JTAG Support
The CYV15G0204RB contains a JTAG port to allow system
level diagnosis of device interconnect. Of the available JTAG
modes, boundary scan, and bypass are supported. This
capability is present only on the LVTTL inputs and outputs and
the TRGCLKx± clock input. The high-speed serial inputs and
outputs are not part of the JTAG test chain.

BIST Data Compare. Character compared correctly.
BIST Last Good. Last Character of BIST sequence detected and valid.
Reserved.
BIST Last Bad. Last Character of BIST sequence detected 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.
BIST Error. While comparing characters, a mismatch was found in one or more of the
character bits.
BIST Wait. The receiver is comparing characters. but has not yet found the start of BIST
character to enable the LFSR.
