Figure 18. LatticeXP2 Datasheet Note
3.
Reason: The JTAG port is designed to be all powerful so that even the PROGRAMN pin is disabled to pre-
vent the pin from interrupting the JTAG port operations.
Work-around Solution: Use the JTAG Refresh instruction to reboot instead of toggling the PROGRAMN
pin.
When the standard security fuse is set, use Background Mode to reprogram the LatticeXP2 device will fail
verification.
Reason: The function of the standard security fuse is for disabling the read back operation. Whenever
powering up the LatticeXP2 device, the security latch latches in the security fuse state to protect the fuse
pattern residing in it. The Background Mode programming by design can not alter or corrupt the current
pattern residing in the SRAM fuse module including the security latches. In other word, the security latch
can’t be cleared by Background operations. As a consequence, the security latch will block all subsequent
Background read back operation.
Work-around Solutions:
A. Skip verification on Background Mode programming.
B. Use Encryption Background Programming.
