I am reading through the Device Profile and noticed a reference to a 32 KHz crystal in the Accumulated Crank Period section. It seems like using a crystal is almost a necessity based on the rollover value of 2048s. I know that the MSP430's source 32 KHz from an external crystal through ACLK. I would be nice to be a able to use the DCO if possible to avoid the external crystal but maybe it's not accurate enough? I am pretty new to this stuff so I was hoping someone could validate my thoughts.
Take care,
Jon
