Could you please give me the test results of the open/short test of the terminal of the QFN32 pin?

Potential Failure Mode
 Pin Open
 Pin Shorted to Ground
 Pin Shorted to adjacent pin (N+1)
 Pin Shorted to Vdd (5V)

Hi Hiroyuki,

1. The JTAG and Reset pins are not modelled explicitly in the FMEDA. 

2. The VDD and VSS pins are modelled in the FMEDA and their Failure modes can be seen in the static version under the name of "Package Contacts"

3. NXP's assumed safety concept recommends not to use XOSC as the system clock source and instead use FIRC. (see the attached Safety Manual Snippet). Therefore the XOSC (and hence its package contacts) are marked NSR in the FMEDA and so not reflected in the Static version of the Clock FMEDA.

Hope this helps!

Thanks!
