| G | in | 17 | XMOD Pin Header / Pushbutton S1 |
| H | out | 16 | XMOD Pin Header / TMS |
| JTAGEN | in | 26 | Enable JTAG access to CPLD for Firmware update (zero: normal IOs, one: CPLD JTAG access). Selectable over S2-1 |
| TCK / ADBUS0 | in | 30 | FTDI |
| TDI / ADBUS1 | in | 32 | FTDI |
| TDO / ADBUS2 | out | 1 | FTDI |
| TMS / ADBUS3 | in | 29 | FTDI |
| ULED | out | 10 | LED D4 (RED) |
| XCLK | in | 4 | 12 MHz OSCI Ref CLK / currently_not_used |
JTAG signals routed directly through the CPLD to 12 pin pinheader. Access between CPLD and pinheader can be multiplexed via JTAGEN (logical one for CPLD, logical zero for pinheader).
UART is routed through the CPLD.
| Output | Input |
|---|---|
| A | BDBUS0 |
| BDBUS1 | B |
ULED D4 (RED) is E xor not G
