6.4.6 Transmission Processing Routine
This routine is executed when TRRQ has been set by the interrupt routine during the execution of master
transmission processing routine 1 (see
6.4.4 (1)
), master transmission processing routine 2 (see
6.4.4 (2)
), or the
slave data transmission processing routine (see
6.4.5
).
Fig. 6-11 shows the flow of the transmission processing routine.
