Event from I2C driver indicating successfull recipt of byte causes transition back to S13 or forward to S15 until the "byte count" (already sent) reaches zero. Each time a transition to S13 is performed, the byte received from the I2C driver is appended to the input block and the "byte count" is decremented. The state transition function used is "STF_S_rd_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 S13 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"
