57.9.3.10 SMBus Quick Command (Host Mode Only)

The TWI interface can perform a quick command:

  1. Configure Host mode (DADR, CKDIV, etc).
  2. Write the FLEX_TWI_MMR.MREAD bit at the value of the one-bit command to be sent.
  3. Start the transfer by setting the FLEX_TWI_CR.QUICK bit.
Note: If an alternative command is used (ACMEN bit = 1), the DATAL field must be cleared.
