Figure 4.60 MIDI IN section and interrupt generation section

MOFULL (R); Midi Output FULL
Data output If all 4 bytes of the MIDI-OUT buffer contain data, "MOFULL" becomes "1B", indicating that there is no free space in the buffer.

MOEMP (R); Midi Output EMPty
When all the data in the MIDI-OUT buffer is discharged, or when no data is transferred to the MIDI buffer, "MOEMP" becomes "1B", indicating that the buffer is empty The At the same time, it is possible to inform the CPU that it is empty by an interrupt.
Figure 4.61 shows MIDI-OUT and the interrupt generation part.
