Hi,
We observe that the timing of units are drifting more than normal. Some of the units are slower while other units run faster than the correct time. The sample size is 5 units.
We make use of the MSP430's RTC_A module for time keeping. Also we have an external 32.768 KHz Crystal connected to XIN/XOUT (Pin 13 & 14) and use it as source for XT1 in LF mode.
The crystal spec is below.
Can you let us know what could be contributing to this timing drift? Any pointers on what is to be taken care of from software/registers point of view Do let us know if you need any other information.
