Read/Write Operation

A TWIHS high-speed frame always begins with the following sequence:

  1. 1.START condition (S)
  2. 2.Master Code (0000 1XXX)
  3. 3.Not-acknowledge (NACK)

When the TWIHS is programmed in Slave mode and TWIHS High-speed mode is activated, master code matching is activated and internal timings are set to match the TWIHS High-speed mode requirements.
