Lattice Semiconductor
Adjacent to JP25-27 are current sense resistors. These permit the measurement of the current flowing from each
of the power supplies. A single resistor can be moved to permit 1.2V, 3.3V, or V

Programmability
The programming interface for the MachXO (and ispClock5610) is located in the northwest corner of the board.
The 1x10 header, JP7, is the connection point for the JTAG download cable. Jumpers JP6 and JP8 determine how
the TDI/TDO chain and TMS pins behave.
Important Note: The board must be un-powered when connecting, disconnecting, or reconnecting the ispDOWN-
LOAD Cable. Always connect the ispDOWNLOAD Cable's GND pin (black wire), before connecting any other JTAG
pins. Failure to follow these procedures can in result in damage to the MachXO device and render the board inop-
erable.
