Functional Description
JTAG
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) on JM1-89.
Reset
PROG_B is nRST_SC0 and PG_ALL and EN_SC3 after power on delay.
Power
Power Good (STAT_SC2) is PGALL and EN_SC3.
PWR_DIS is high impedance.
USER IO
MODE_SC1 is connected to XBSC.
XA_SC is connected to UFL.
LED
Green LED D4
| Status | Description |
|---|---|
| On | Done is low, FPGA not programmed |
| OFF | Done is high, FPGA is programmed |
