Event from I2C driver indicating successfull transmition of byte causes transition back to S14 or forward to S15 until the "byte count" (already sent) reaches zero. Each time a transition to S14 is performed, the next byte in the output block is sent and the "byte count" is decremented. The state transition function used is "STF_S_wt_data".

When the "byte count" reaches zero the "STF_S_rd_data" state transition function generates an "event_transfer_complete" event that causes a transition to S15. The state transition function used when going from S14 to S15 is STF_S_TRANSFER_COMPLETE.

Event from I2C driver indicating failure in receipt causes transition to S15. The state transition function used is "STF_S_wait_for_stop"

Event from I2C driver indicating unexpected stop condition seen causes transition to S1. The state transition function used is "STF_S_ready"
