JTAG signals routed directly through the CPLD to FPGA. Access between CPLD and FPGA can be multiplexed via JTAGEN (logical one for CPLD, logical zero for FPGA).
Boot Mode is selected via B2B Pin Mode. See Table 11.1 Boot Modes from Xilinx ug1085.
Mode | Description |
---|---|
Zero | Boot from SD |
On | Boot from Flash |
PGOOD is EN1 and not ER_OUT. There is no additional power management.

X0 | PHY_LED1 |
X1 | ERR_OUT or ERR_STATUS or MODE |
