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.

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 Figure 1-6. JTAG configuration is allowable at any time under any mode pin setting. JTAG initiated configuration takes priority over the mode pin settings.
