45.6.3.11 SMBus Quick Command (Host Mode Only)

The TWIHS can perform a quick command by following these steps:

  1. Configure the Host mode (DADR, CKDIV, etc).
  2. Write TWIHS_MMR.MREAD at the value of the one-bit command to be sent.
  3. Start the transfer by setting TWIHS_CR.QUICK.

If alternative command is used (ACMEN bit set to ‘1’), DATAL field must be set to 0.
