6. USB JTAG
JTAG configuration is provided through onboard USB-to-JTAG configuration logic where
a computer host accesses the SP605 JTAG chain through a Type-A (computer host side) to
Type-Mini-B (SP605 side) USB cable. The JTAG chain of the board is illustrated in
. JTAG configuration is allowable at any time under any mode pin setting. JTAG
initiated configuration takes priority over the mode pin settings.
FMC bypass jumper J19 must be connected between pins 1-2 (bypass) to enable JTAG
access to the FPGA on the basic SP605 board (without FMC expansion modules installed),

Notes:
1. U17 System ACE CF controller 3.3V signals as named are wired to a set of TXB0108 3.3V-to-1.5V level
shifters. The nets between the 1.5V side of the level shifters and the U1 FPGA have the same names
with _LS appended.
2. The System ACE CF clock is sourced from U29 32.000MHz oscillator.
