The state service examples show the typical actions that must be performed in response
to the 26 I
associated state services can be omitted, as long as care is taken that the those states
can never occur.
In an application, it may be desirable to implement some kind of timeout during I
operations, in order to trap an inoperative bus or a lost service routine.
Example to initialize I
Begin a Master Transmit operation by setting up the buffer, pointer, and data count, then
initiating a START.
