Missing SPI Clock and data bytes after wake-up from low power mode (LPM)
After device wake-up from a low power state, the SPI module can not properly propagate the first few clock cycles and data bits of the first byte sent out.
To maintain SPI data integrity after a wakeup, use the following sequence when entering and exiting LPMs:
1.Disable SPI module
2.Wait for Interrupt(WFI)- enter LPM
3.Wake up from LPM (any source).
4.Enable the SPI module.
