| TMS / M_TMS | in | 29 | B2B JTAG |
| XIO | out | 20 | FPGA IO from Bank14 H26 / 24.18MHz CLK from CPLD internal Osc. |
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.
PROG_B is RESIN and PG_ALL.
PG_ALL is used for PROG_B Reset and LED.
LED D4
| Status | Condition | Description |
|---|---|---|
| ON | RESIN=0 | external Reset is set |
| fast blink | PG_ALL=0 | PG_ALL Problem (1.8V) |
| slow blink | DONE=0 | FPGA not programmed |
| very slow blink | ready |
