63.9.5.4.4.2 — Clock Stretching in Write Mode

The clock is tied low if the internal shifter and FLEX_TWI_RHR are full. If a STOP or REPEATED_START condition was not detected, it is tied low until FLEX_TWI_RHR is read.

The following figure describes the clock stretching in Write mode.

  2. SCLWS is automatically set when the clock stretching mechanism is started and automatically reset when the mechanism is finished.
