• Manufacturer Part Number: ml2215
• Description: Speech Synthesizer Plus Music Lsi With On-chip 3 Mbit Mask Rom
• Manufacturer: Oki Semiconductor

(3) End-Bit
The end-bit is set at the first byte, the MSB, of music phrase data. As soon as the LSI starts to output the last note
code where the end-bit is set to “1”, the Music Generator circuit issues an end-music interrupt call and stops
playback after the last note code has been output.
8.3 Sample Musical Note Codes
Table 8.6 shows sample codes to output a part of musical score shown in Figure 8.3.
Note: * Bit 6 of the first byte can be either “0” or “1” (Don’t care bit), so is set to “0” in the above sample
