Functional Description
JTAG
Power
...
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).
Reset
RESIN is connected to PROG_B.
PUD_C
PUD_C is set to zero.
LED
Green LED D1.
| Status | Priority | Description |
|---|---|---|
| ON | 1 | B2B Reset is set |
| Blinking | 2 | Don is low (FPGA not programmed) |
| User Defined | 3 | XIO is connected to LED |
