Name / opt. VHD Name | Direction | Pin | Pullup/Down | Bank Power | Description |
---|---|---|---|---|---|
C_LED | out | 17 | 3.3V | Green LED D4, blinking pattern according to different states | |
DONE | in | 28 | 3.3V | FPGA Done signal, also connected to green LED D3. Is OFF when FPGA configured. | |
F_TCK / C_TCK | out | 9 | 3.3V | FPGA JTAG | |
F_TDI / C_TDI | out | 21 | 3.3V | FPGA JTAG | |
F_TDO / C_TDO | in | 5 | 3.3V | FPGA JTAG | |
F_TMS / C_TMS | out | 4 | 3.3V | FPGA JTAG | |
GND | 10 | 3.3V | GND | ||
GND | 11 | 3.3V | GND | ||
GND | 12 | 3.3V | GND | ||
GND | 13 | 3.3V | GND | ||
GND | 14 | 3.3V | connected to GND | ||
JTAGMODE | 26 | 3.3V | Enable JTAG access to CPLD for Firmware update ( LOW-'0' : JTAG signales routed to module, HIGH-'1' : CPLD access) | ||
MODE | in | 16 | 3.3V | / currently_not_used | |
PG_ALL | in | 27 | 3.3V | Power sense from 1V/1.8V/3.3V/3.3VIN | |
PGOOD | inout | 25 | 3.3V | Power Good. Low, if power failed, internal pullup activated | |
PROG_B | out | 23 | 3.3V | FPGA Prog_B | |
RESIN | in | 8 | 3.3V | external reset from B2B | |
TCK / M_TCK | in | 30 | 3.3V | B2B JTAG | |
TDI / M_TDI | in | 32 | 3.3V | B2B JTAG | |
TDO / M_TDO | out | 1 | 3.3V | B2B JTAG | |
TMS / M_TMS | in | 29 | 3.3V | B2B JTAG | |
XIO | out | 20 | 3.3V | FPGA IO from Bank14 H26, Can be used to control LED D4 if no error state occurs |
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.
PGOOD is set low, if PG_ALL failed otherwise high impedance. Internal pullup is activated.
PGOOD can be drive to low from carrier, this will be indicated by LED subsequency only.
