It looks like the programmer supports in-circuit programming for the MMPF0100.  Fig. 4 of KTPFPGMEVMEUG shows that I2C and VIN connections on the MMPF0100 are required.  Questions / issues:

1.  If the CPU is not powered, will pullups on I2C cause problems on the CPU?

2.  VDDIO must be connected to VIN, which is not the normal connection on the board.

Do most customers use the socket to program the MMPF0100, and then solder it on the board?  This won't allow testing of the configuration, but it will avoid the issues above.
