Figure 20-1 shows the configuration of the melody driver.
This LSI includes one channel of the melody driver.
To use the melody driver, the secondary function of Port 2 or Port 5 should be set. For the secondary function of Port 2,
see Chapter 15, "Port 2". For the secondary function of Port 5, see Chapter 18, "Port 5".For the clock to be used in this
block, see Chapter 6, "Clock Generation Circuit".
