7.2.6. Power Supply
3.3 V and 1.2 V power supply rails are converted from the USB 5 V interface when the Board is connected to a host PC.
7.2.7. Test Points
In order to check the various voltage levels used, test points are provided:
TP1: +3.3 V
TP2: +1.2 V
TP3: GND
7.2.8. USB Programming and Debug Interface
The USB mini-B socket of the MachXO3D Breakout Board serves as the programming and debug interface.
JTAG Programming: For JTAG programming, a pre-programmed USB PHY peripheral controller is provided on the
MachXO3D Breakout Board to serve as the programming interface to the MachXO3D FPGA.
Programming requires the Lattice Diamond or ispVM System software.
