Oscillator fault forced in bypass mode when P2SEL.7 bit is not set
When the LFXT1 oscillator is used in bypass mode and P2SEL.7 is not set, the oscillator fault flag (OFIFG) will be forced to set and cannot be cleared. Due to the failsafe logic, LFXT1 cannot be used as MCLK in this case. The bug only affects the behavior of the oscillator fault, the clocking itself works properly.
Set both P2SEL.6 and P2SEL.7 if the application requires correct function of the oscillator fault flag (e.g. MCLK failsafe logic).
