Hello,
This has reference to the MSP430F2617 errata sheet. It mentions the following problems XOSC5, XOSC6 and XOSC8.
As an example, XOSC5 is stated below:
"Function LF crystal failures may not be properly detected by the oscillator fault circuitry Description The oscillator fault error detection of the LFXT1 oscillator in low frequency mode (XTS = 0) may not work reliably causing a failing crystal to go undetected by the CPU, i.e. OFIFG will not be set."
I have the following question regarding this:
What does "failing crystal" mean? Does it mean that there is no oscillation at all?
If so, does it mean that the crystal may not be producing oscillations and yet there is not fault detection by the MSP controller?
What other crystal failure modes exist which go undetected due to XOSC5?
Thanks,
Manohar
