(2) The digital clock input (LFCLK_IN) accepts a logic level square wave clock.
(3) The LFCLK monitor may be used to monitor the LFXT or LFCLK_IN. It will always fault below the MIN fault frequency, and will never
fault above the MAX fault frequency.

(2) The HFXT startup time (t
start, HFXT
) is measured from the time the HFXT is enabled until stable oscillation for a typical crystal. Start-up
time is dependent upon crystal frequency and crystal specifications. Refer to the HFXT section of the MSPM0 G-Series 80-MHz
Microcontrollers Technical Reference Manual.Current consumption increases with higher RSEL and start up time is decreases with
higher RSEL.
(3) The digital clock input (HFCLK_IN) accepts a logic level square wave clock.
