1) If the oscillator calibration values are saved in the
information memory and this memory is not going to
be re-programmed (erased) during programming, the
device should be programmed with the Cal Int. RC
(=calibrated internal RC oscillator) option selected in
the FORTE programmer settings window. In the
other cases Not Cal Int. RC (=not calibrated internal
RC oscillator) should be selected.

1) Pin P feeds the device with 6.5V during the fuse
programming. If the fuse is not to be programmed,
this pin does not have to be connected.
2) The MSP430F5xxx and CC430 devices lock in a
different way, i.e. pin P stays disconnected. Even the
100 R resistor can be left out in such a case.
3) If the oscillator calibration values are saved in the
information memory and this memory is not going to
be re-programmed (erased) during the programming
process, the device should be programmed with the
Cal Int. RC (=calibrated internal RC oscillator)
option selected in the FORTE programmer
settings window. In other cases Not Cal Int. RC
(=not calibrated internal RC oscillator) should be
selected.
