Function

Oscillator fault forced in bypass mode when P2SEL.7 bit is not set

Description

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.

Workaround

Set both P2SEL.6 and P2SEL.7 if the application requires  correct function of the oscillator fault flag (e.g. MCLK failsafe logic).

Note: Setting P2SEL.7 bit disables the GPIO functionality and enables the input schmitt trigger of the pin. P2.7 should be tied to a fixed voltage level (VCC or GND) to prevent cross current.
