6.14 SPI_ERR_02

SPI Clock and data bytes after wake-up from low power mode (LPM) are missed

Revisions Affected

B

Details

After device wake-up from a low power state, the SPI module may not properly propagate the first few clock cycles and data bits of the first byte sent out.

Workaround

To ensure SPI data integrity after a wakeup, use the following sequence when entering and exiting LPMs:

  • Disable SPI module
  • Wait for Interrupt(WFI)- enter LPM
  • Wake up from LPM (any source).
  • Enable the SPI module.
