LCD Clock Inputs & Reset Behavior
The LCD clock input can from main OSC (OSCCLK) or 32 kHz OSC (OSCCLK_32K), refer to Reference
Manual for detailed information. In case the clock source is from main OSC, after reset, the main OSC will
be disabled and must be enabled by setting the OSCE in CPMU as soon as possible in order to have clock
available for the LCD. If clock source is OSCCLK_32K, software must wait the OSC startup time before
enabling the LCD. If 32K OSC is enabled, it will be always on until a power on reset happens.
