This LSI includes 4-bit Port 2 (P20 to P22, and P24) dedicated to output.
Port 2 can output low-speed clock (LSCLK), high-speed clock (OUTCLK), melody, and PWM waveform as a secondary
function. For the clock output, see Chapter 6, "Clock Generation Circuit." For the Melody 0 (MD0) output, see Chapter
20, "Melody Driver." For the PWM (PWM0) output, see Chapter 10, "PWM."
Figure 15-1 shows the configuration of Port 2.
