At power-up and on reset.
At power-up, the FPGA is not configured and is waiting for a bit stream to be loaded.
By fitting Jumper J1 (Figure 8 - Connector Location.), it will allow the bit stream
stored into the PROM to be loaded into the FPGA at power-up and after every TIM
reset.
If J1 is not fitted, nothing happens. This condition is useful when needing to configure
the FPGA via JTAG.
Also at power-up and on a carrier board reset signal, the SMT364 expects receiving
a dummy ComPort word (any value) and sends one back containing the Firmware
version number. It is a way of checking that the firmware is latest and that the board
is responding and ready to work. The format of that ComPort word is as follow:
0xFF364Fxy, which means FPGA firmware version x.y
