Hello,
I am working in FMEA regarding failures that can occur at pin level such as short to GND, to supply or adjacent pins.
Your services send us a fmea excel file in which is stated that in case of short circuit of VCP_LSD to VCPH pin the SPI communication will be lost.
Why do we lose the SPI communication ? is it an error ?
The DVDD block is supplied by AVDD that’s supplied by PVDD, there is no interaction with the charge pump !
