23.1.3
This LSI includes one channel of the melody driver.
To use the melody driver, the secondary function of port 2 should be set. For the secondary function of port 2, see
Chapter 19, "Port 2". For the clock to be used in this melody driver, see Chapter 6, "Clock Generation Circuit".
• In melody output mode, 29 scales (melody audio frequency: 508Hz to 32.768kHz), 63 tone lengths, and 15 tempos) are
• In buzzer output mode, 4 output modes, 8 frequencies, and 15 duties can be set.
Figure 23-1 shows the configuration of the melody driver.
