1) Pin P feeds the device with 6.5 V during the fuse
programming. If the fuse is not to be programmed,
this ping 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 the other cases Not Cal Int. RC
(=not calibrated internal RC oscillator) should be
selected. There is no need to select the oscillator for
the MSP430F5xxx and CC430 devices.
4) Speed in the FORTE programmer settings window
should be slow down if any external capacitor is
connected to the device's reset pin.
5) The FORTE programmer also erases the Segment A of
the information memory with the EraseSegmentA
option selected.
