Is there a possibility to get the LFXT1 oscillator to use an external 32-kHz clock ?
There is no BYPASS bit ( or the like) whatever in the LFXT1 control registers.
"LFXT1 may be used with an external clock signal on the XIN pin when
XTS_FLL = 1. The input frequency range is ~1 Hz to 8 MHz. When the input
frequency is below 450 kHz, the XT1OF bit may be set to prevent the CPU from
being clocked from the external frequency."
With the XT1OF bit occasionally set, I suspect there is hardly a possibility to use an external 32-kHz clock to drive the MSP430F412.
Is this the case?
